Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls.
What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answer:
81/792 or 9/88 or 10.2%
Step-by-step explanation:
Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3
3 * 3 * 3 * 3 = 81
81/792 simplified is 9/88 percentage is 10.22%
The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total numbers of balls are 12.
Each color has 3 balls.
If total 12 balls are tossed, the number of ways of catching 5 of them is,
¹²C₅ = 792
The number of ways of catching 2 red balls out of 3 is ³C₂ = 3
The number of ways of catching 1 green ball out of 3 is ³C₁ = 3
The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3
The number of ways of catching 1 white ball out of 3 is ³C₁ = 3
Thus, the probability as per the question is given as follows,
(3 × 3 × 3 × 3)/792
= 81/792
= 0.1025
Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

At a grocery store, bananas cost $1.60 per pound. Today there is a 10% discount. How much would 4 1/2 pounds of bananas cost with the discount? Show work or explain how you reached your answer.
Answer:
$6.48
Step-by-step explanation:
The discount is 10%. That means you pay 90% of the price.
At the regular price, 4 1/2 lb of bananas cost:
$1.60/lb * 4.5 lb = $7.20
Since with the 10% discount, you pay 90% of the original price, now we calculate 90% of the original price.
90% of $7.20 = 0.9 * $7.20 = $6.48
Answer: 4.5 lb cost $6.48 with the 10% discount
A rectangular prisim has a base with an area of 200cm squared. The volume of the prism is 3,000cm cubed. What is the height of the prism?
Answer:
[tex]Height = 15cm[/tex]
Step-by-step explanation:
Given
[tex]Base\ Area = 200cm^2[/tex]
[tex]Volume = 3000cm^3[/tex]
Required
The height
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
This gives
[tex]Height = \frac{3000cm^3}{200cm^2}[/tex]
[tex]Height = \frac{3000}{200}cm[/tex]
[tex]Height = 15cm[/tex]

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every
morning. His goal is to run at least 6 miles by the end of the week.
Which inequality represents the least number of days after Monday that Joseph needs to run
to reach his goal? *
Answer:
2 + 1 1/3x ≥ 6
x ≥ 3 days
Step-by-step explanation:
Monday = 2 miles
Other days = 1 1/3 miles
x = least number of days after Monday that Joseph needs to run
to reach his goal
Total miles = 6 miles
The inequality is
2 + 1 1/3x ≥ 6
1 1/3x ≥ 6 - 2
1 1/3x ≥ 4
4/3x ≥ 4
Divide both sides by 4/3
4/3x ÷ 4/3 ≥ 4 ÷ 4/3
x ≥ 4 × 3/4
x ≥ 3 days

arc m BY=41°
it is a central angle,
its inscribed angle is half of its=41/2=20.5°
we know that
tangent in the circle is perpendicular to the center,so
∡BAC=90°
∡BAY+∡YAC=90°

Area = 30 ft × 40 ft
Area = 1200 ft²
Now let us find the area of the backyard.
Area = l × w
Area = 80 ft × 50 ft
Area = 4000 ft²
Now that we have found the area of the house and the backyard, it asks us to find the total area of house and the backyard. To find the answer, you will both, the area of house and the area of the backyard.
Area of house + Area of backyard

7x-5y=15
solve for y, please help
Answer:
7x-15/5
Step-by-step explanation:
Given :-
A linear equation in two variable is given to us . That is 7x - 5y = 15.And , we need to solve for y in terms of x . So taking the given equation ,
[tex]:\implies[/tex] 7x - 5y = 15
[tex]:\implies[/tex] -5y = 15 - 7x
[tex]:\implies[/tex] 5y = 7x - 15
[tex]:\implies[/tex] y = ( 7x - 15)/5
Hence the required answer is 7x-15/5.tep Looking at the powers of 3 shown, it is clear that each power may be found by multiplying the previous power by 3. Or you can also see that each power may be found by dividing the power after it by 3. Using this pattern, what must 31 equal?
