Question 59173: Records at a particular bank show that if a customer at the bank is randomly selected, the probability that the customer has a savings account at the bank is 0.42, the probability that the customer has a checking account at the bank is 0.74, and the probability that the customer has both is 0.28. If a customer is randomly selected, find the probability that he/she has:

a) A checking account given that the customer has a savings account

b) A savings account given that the customer has a checking account

find the probability that he/she has:
a) A checking account given that the customer has a savings account
P(c|s)=[P(c and s)]/[P(s)] = 0.28/0.42
-------------------------
b) A savings account given that the customer has a checking account
P(s|c)=[P(c and s)]/[P(c)]=0.28/0.74
------------------
