Answer:
13 / 19
Step-by-step explanation:
Given that :
U = 130
Let :
s = swimming pool
t = track
g = gym
n(g) = 61 ; n(s) = 68 ; n(t) = 60
n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19
n(g n s n t) = 6
n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13
Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)
= 13 / 19
= 13 / 19
45/9 or 45 divided by 9 is equal to 5 because
9 times 5 is equal to 45.
Use the app Socratic, it gives u a step by sort explaination
So first 15/100 which is 15 percent and out of 20, thats 15.
20. 100. 100X15 divided by 20 which is 75. I did cross multiplication ok. So I just did 20 times 15 and then divided by 100
