Question

At the avonelea country club,72% of the members play bridge and swim, and 76% play in bridge . If a member is selected at random , find the probability that the number of swims given that member plays bridge . Please round the final answer to 2 or 3 decimal places

Answer 1

0.947

Explanation:

Given that :

Play bridge and swim = 72%

Play bridge = 76%

Let play bridge = B

Swim = S

Thus ;

P(B n S) = 0.72

P(B) = 0.76

Probability that member swims given that member plays bridge

P(S | B) = P(BnS) / P(B)

P(S | B) = 0.72 / 0.76

P(S | B) = 0.947
