Problem 32CQ
Bowling and Club Membership Of the members of the Spring Lake Bowling Lanes, 57% have a lifetime membership and bowl regularly (three or more times a week). If 70% of the club members bowl regularly, find the probability that a randomly selected member is a lifetime member, given that he or she bowls regularly.
ANSWER:
Solution:
Step 1 of 2:
Let us denote the event A = lifetime membership
Let the event B = regular bowling (3 or more times a week).
And let the = lifetime membership and regular bowling.
Then,
P(B) = 0.7
P() = 0.57
Here we have to find the probability that a randomly selected member is a lifetime member, given that he or she bowls regularly.
