Your call center receives many different types of calls Requ

Your call center receives many different types of calls. Requests for information account for 60% of all calls, while 30% of all calls result in an actual order. Of the calls that do not involve an information request, 50% result in an order.

(c) What is the probability that a call generated an order and did not request information?

Solution

P(request for info) = 60%

P(actual order) = 30%

P(order | no request for info) = 50%

P(order | no request for info) = P(order and no request for info) / P(no request for info)

50% = P(order and request for info) / 40%

Crossmultiplying :

P(order and request for info) = 50% * 40%

P(order and request for info) = 20% ---> ANSWER
