The probability that you have seen both the red and green marbles at least once is 0.3104
Given,
1/5 chance of winning a marble of any color in a drawing.
Every draw is independent and has the same probability because the marbles are replaced.
Calculating = 1- the likelihood of not receiving both red and green marbles in any of the four draws yields the same result as P, the probability of receiving both red and green marbles at least once (Q).
The union of the following three examples represents ways to not receive both red and green in all four draws:
(1)
Probability of no red and no green in a draw = 3/5.
Probability of no red and no green in 4 draws,
Q1 = 3/5 * 3/5 * 3/5* 3/5 = 81/54
The probabilities are multiplied as each draw is independent and has the same probabilities.
(2)
The probability of no red and 1 green in 4 draws is given by binomial probability.
= (4 3) (1/5)(3/5)³ = (4 * 3³)/5¹ = 108/5⁴
The probability of no red and 2 green in 4 draws is given by binomial probability.
= (4 2) (1/5)²(3/5)² == (6 * 3²)/54 = 54/5⁴
The probability of no red and 3 green in 4 draws is given by binomial probability.
= (4 3) (1/5)³(3/5) == (4 * 3)/5¹ = 12/5⁴
The probability of no red and 4 green in 4 draws is given by binomial probability.
= (4 4) = 1 * 1/5¹ = 1/5⁴⁴
Q2= sum of all 4 above probabilities.
Q2 (108 +54 + 12+1)/5 = 175/5⁴
(3)
This probability is the same as in Q2. Q3 = 175/5⁴
Therefore the probability of not seeing both red and green at all,
Q = Q1 + Q2 + Q3.
= 81 +175 + 175/5⁴ = 413/5⁴
Finally, the probability of getting both red and green at least once,
P = 1 - Q
= 1-413/5⁴
= (625 431)/625
= 194/625
= 0.3104.
The answer is 0.3104.

The value of x in the given function, f(x) = 3/2x - 4 when f(x) = 5, is x = 6
Determining the value of x in a functionFrom the question, we are to determine the value of x in the given function for the given value of f(x).
The given function is
f(x) = 3/2x - 4
and
f(x) = 5
Now, to determine the value of x, put f(x) = 5 in the given function
f(x) = 3/2x - 4
5 = 3/2x - 4
Add 4 to both sides of the equation
5 + 4 = 3/2x - 4 + 4
9 = 3/2x
Multiply both sides by 2
2 × 9 = 2 × 3/2x
18 = 3x
Divide both sides by 3
18/3 = 3x/3
6 = x
Therefore,
x = 6
Hence, the value of x is 6

Write an equation of the line that passes through (-6, 0) and (0, -24) .
Answer: y= -4x -24
Step-by-step explanation:
The equation is y=mx + b
We know the b is -24 because it already tells us the coordinate of the y-intercept is (0, -24), so we only need to find x by looking at the rise over run.
The rise is -24, and the run is 6, so -24/6 = -4
So the equation is y= -4x -24

The odds against selecting a history are 31/16.
Define probability.Probability is the concept that describes the likelihood of an event occurring. In many situations, it is necessary to foresee how something will turn out in the actual world. We may be aware of the result of an event or not. When this occurs, we state that there is a possibility that the event will occur.
Probability is the ratio of the most likely outcomes to all other possible outcomes of an event. The number of successful outcomes for an experiment with 'n' outcomes may be expressed using the symbol x. The following formula can be used to determine the likelihood of an event.
Probability(Event) = favorable outcome/Total outcome = x/n
Number of playwrights = 47
Number of tragedies = 16
Therefore, the odds against selecting tragedies are
(47 - 16) / 16
= 31/16

New game You pay 10 and roll a 6 die. If you get a you win 50 If not, you get to roll again. If you get a 6 this time, you get your 10 back.
a) Create a probability model for this game.
b) Find the expected value and standard deviation of your prospective winnings.
c) You play this game five times. Find the expected value and standard deviation of your average winnings.
d) 100 people play this game. What's the probability the person running the game makes a profit?
a) Probability model
P(40) = 1/6
P(0) = 5/36
P(-10) = 25/36
b) E(X) = -5/18
standard deviation = 18.331
c) standard deviation = 91.65
d) Probability = 0.560
From the question, we have
a) X = -10, 0 or 40 for your winnings (or losses). The corresponding probabilities are:
P(40) = 1/6
P(0) = (5/6)(1/6) = 5/36
P(-10) = 1 - 1/6 - 5/36 = 25/36
b) E(X) = (-10)(25/36) + 0(5/36) + 40(1/6) = -5/18
E(X^2) = (100)(25/36) + 1600(1/6) = 3025 / 9
Var(X) = E(X^2) - [E(X)]^2 = 3025 / 9 - (-5/18)^2 = 108875 / 324
standard deviation = sqrt [Var X] = 119043 / 6494 =18.331
c) E(X) = (-10)(25/36) + 0(5/36) + 40(1/6) = -5/18
5 * E(X) = - 25/18
standard deviation = 5 * 18.331 = 91.65
d) Probability :
P(X < 0) = P{ z < [0 - (-5/18)] / [(119043 / 6494) / sqrt 100] } = P(z < 0.1515) = 0.560

Possibility is referred to as probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty.

Use the given zero to find the remaining zeros of each function.
Thank you!! :)
Answer:
remaining zeros: {-1/2, √3}
Step-by-step explanation:
Given the polynomial function f(x) = 2x³ +x² -6x -3 has one zero at x = -√3, you want the remaining zeros.
Conjugate zerosA polynomial with rational real coefficients and zeros that are roots or complex numbers will have all such roots in conjugate pairs.
The root that is the conjugate of -√3 is +√3.
Product of rootsThe product of the roots of an odd-degree polynomial will be the opposite of the ratio of the constant to the leading coefficient. Here, that means the product of roots is ...
-(-3/2) = 3/2
We already know that two of the three roots are ±√3, so their product is -3. The remaining root will be ...
(3/2)/(-3) = -1/2
The remaining zeros of f(x) are √3 and -1/2.
__
Additional comment
When the degree of the polynomial is even, the constant term will be the product of the roots. This odd/negative, even/positive behavior comes from the fact that each zero (q) corresponds to a factor (x -q).
The product of these binomial factor constants is the constant in the standard-form polynomial. It will have a negative sign if there are an odd number of factors.

19. a television set is on sale for 15% off the original price. if the sale is $340, what was the original price of the televisions set?
Using the percentage method, we know that the original price of the TV set was $400.
What is the percentage?Percentages are just fractions with a denominator of 100.
To show that a number is a percentage, we place the percent sign (%) next to it.
For instance, if you properly answered 75 out of 100 questions on a test, you would have received a 75% grade (75/100).
So, we know that the percentage is always out of 100.
Then we automatically know that:
100% - 15% = 85%
We know:
85% = $340
15% = ?
Now, calculate the reduced price as follows:
85/340 = 15/x
85x = 15(340)
85x = 5,100
x = 5100/85
x = $60
Original price of the TV set:
Sold cost + Reduced cost
$340 + $60
$400
Therefore, using the percentage method, we know that the original price of the TV set was $400.

Discrete 5 dice of different colors are rolled, and the number coming up on each dice is recorded.
Since all the dice are of different colors.
So any combination of the numbers on the dice is unique.
Dice has numbers 1 to 6.
So, for each dice there are 6 possibilities.
Since number coming on a dice is independent to the number coming on the another dice.
So, total different outcomes are = 6 x 6 x 6 x 6 x 6 = 6^5 = 7776.
Hence, the number of total different outcomes are, 7,776.

a country uses as currency coins with values of 1 peso, 2 pesos, 5 pesos, and 10 pesos and bills with values of 5 pesos, 10 pesos, 20 pesos, 50 pesos, and 100 pesos. find a recurrence relation for the number of ways to pay a bill of n pesos if the order in which the coins and bills are paid matters
when we pay n pesos, then recurrence relation for all the number are in a ways to pay a bill is in this order:[tex]a_{n} =a_{n-1}+a_{n-2}+2a_{n-5}+2a_{n-10}+ a_{n-20}+a_{n-50}+a_{n-100}[/tex]
A recurrence relation is an equation which represents a chain primarily based totally on a few rule. It enables in locating the following time period (subsequent time period) established upon the previous time period (preceding time period). If we recognise the preceding time period in a given series, then we will without difficulty decide the following time period.
Recurrence family members are used to lessen complex issues to an iterative procedure primarily based totally on less difficult variations of the trouble. An instance trouble wherein this technique may be used is the Tower of Hanoi puzzle. Recurrent is some thing that happens frequently or repeatedly. However, in case you are speakme approximately a recurrence relation, then you definitely have a mathematical shape which you are handling and it's miles really specific than a recursive formula. Recursion is the repeated use of a process or action.
pay 1 pesos coin , then n-1 pesos
pay 2 pesos coin , then n-2 pesos if n ≥ 2
pay 5 pesos coin , then n-5 pesos if n ≥ 5
pay 10 pesos coin , then n-10 pesos if n ≥ 10

Find the distance from line L to point P for each of the following: Line L contains points (-5,3) and (4,-6). Point P(2,4)
Answer and explanation in one:
(4+9)/(-2-1) = 13/-3 = -13/3
y=-13x/3 + b
4=26/3 + b
b = 4-26/3 = (12-26)/3 = -14/3
y=-13x/3 -14/3 is the line through the two given points
find the line perpendicular and through (14,-6)
y=3x/13 + b, plug in the point to find b
-6 = 3(14)/13 + b
b = -6 -42/13 = -78/13 - 42/13 = -120/3
y= 3x/13 - 120/13
find the intersection point of the two lines, set them equal
3x/13 -120/13 = -13x/3 - 14/3
multiply by 39
9x - 360 = -169x - 182
178x = 360-182 = 178
x = 1
y= -27/3=-9
the point is (1,-9)
calculate the distance from (1,-9) to (14,-6)
d^2 = 9+169 = 178
d = sqr178 = about 13.34
