Question 1053921: A local country club has a membership of 600 and operates facilities that include an 18-hole championship golf course and 12 tennis courts. Before deciding whether to accept new members, the club president would like to know how many members regularly use each facility. A survey of the membership indicates that 64% regularly use the golf course, 46% regularly use the tennis courts, and 9% use neither of these facilities regularly. Given that a randomly selected member uses the tennis courts regularly, find the probability that they also use the golf course regularly.
How can I solve this with a calculator?

64% regularly use the golf course, 46% regularly use the tennis courts, and 9% use neither
1- .06 = .94 do golf, tennis or both
.64 + .46 - .16 = .94
.16 do both
P(A|B) = P(A and B)/P(B)
P(G|T) = .16/.46 = 16/46 = 8/23
