The probability that it has a letter that immediately follows an odd number 1/2. The probability that D is in the code but is not in the first position 1/4.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated.
You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.
The size of the sample space is (8, 16, 20, and 24)
If a code is chosen at random,
The probability that it has a letter that immediately follows an odd number (1/8, 1/6, 1/3, 2/5, 2/3)
= 1/2
If a code is chosen at random,
The probability that D is in the code but is not in the first position (1/8, 1/6, 1/3, 2/5, 2/3)
= 1/4

Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.
Answer:
5
Step-by-step explanation:
To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

Step-by-step explanation:
A jar contains 2 red, 5 green, 2 blue and 6 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a green and then a yellow marble?
Answer:
Step-by-step explanation:
The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:
p = nA / N
then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.
Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:
pG1 = 5/16
Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:
pY2 = 6/16 = 3/8
(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).
Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:
pG1Y2 = pG1 * pG2 = 15/128
What is the equation for this line?

Answer:
$268.38
Step-by-step explanation:
First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.
Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38

According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.
[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)
Whenever dividing fractions, remember this:
SAME, CHANGE, RECIPROCAL (FLIP)
KEEP THE FIRST FRACTION THE SAME
CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN
FLIP THE SECOND FRACTION
[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]
[tex]\frac{42}{6} =7[/tex]
I, therefore, believe Muna will have 7 pieces of string.
