Question 1176843: The financial director of a hardware wholesaler has asked the accountant to ring each customer five days before their account payment is due, as a means of reducing the number of late payments. As a result of time constraints, however, only 60% of customers receive such a call from the accountant. Of the customers called, 90% pay on time, while only 50% of those not called pay on time. The company has just received a payment on time from a customer. What is the probability that the accountant called this customer?

Hi
Made pmt = .9*.6 + .5*.4 = .54 + .20 = .74
P(call|pmt) = P(call ∩ pmt)/P(pmt) = (.6)(.9)/.74 = 54/74 = .7432 0r 74.32%
Wish You the Best in your Studies.
