There is a 70% probability that a pupil who uses the swimming pool and gym will be selected. How do I know this? Well, since 30 pupils use neither, this means at least 50/80 pupils use both. This reduces to 5/8, so 5/8 pupils use both the gym and swimming pool. 5/8 as a decimal is equal to 70%, because 80% would be 6/8, 90% would be 7/8, and 100% would be 8/8.

That’s one way to do it.


Another way to solve this is as follows:

Since 22 pupils use the swimming pool and 34 use the gym, that means 56 pupils use both total. 56/80 reduces to 7/10, which as a decimal is 70% or 0.7.

Your final answer: Probability = 70%

If you need more help, let me know and I will gladly assist you!

A rectangle is twice as long as it is wide. If its area is 50 sq. yd., find the length.
sertanlavr [38]
A = L * W
A = 50
L = 2W

50 = W(2W)
50 = 2W^2
50/2 = W^2
25 = W^2
sqrt 25 = W
5 = W

L = 2W
L = 2(5)
L = 10 <==length is 10 yd
