Answer:
a) 3.6%
Step-by-step explanation:
The given question mixed up, below is the correct question:
The bumper car ride at the state fair has 2 red cars, 4 green cars, and 2 blue cars. Garth is first in line for the ride and is assigned a car at random. Patty is next in line and is randomly assigned a car. Find the probability that both events A and B occur. Express your answer as a percent. If necessary, round your answer to the nearest tenth.
Calculation:
Given that the state fair has 2 red cars, 4 green cars and 2 blue cars.
There are therefore 2+4+2 = 8 cars in total.
Probability that Events A occurs P(A) = = 4
Probability that Events B occurs P(B) =
Probability that Events A and B occur P(A ∩ B) = ×
=
= 0.0357 = 3.57% ≈ 3.6%
Therefore, the probability that both events A and B occur is 3.6%
Answer:
The length of Louise’s basement is <u>90 feet</u>.
Step-by-step explanation:
Given:
Louis wants to carpet the rectangular floor of his basement.
The basement has an area of 4860 square feet.
The width of the basement is 3/5 it’s length.
Now, to find the length of Louise’s basement.
Let the length of basement be
So, the width is:
Area of the basement = 4860 square feet.
Now, to get the width of basement we put formula:
<em>Multiplying both sides by 5 we get:</em>
<em>Dividing both sides by 3 we get:</em>
<em>Using square root on both sides we get:</em>
Therefore, the length of Louise’s basement is 90 feet.
