Two shipments (A and B) of blenders were inspected. Shipment A contains 50 blenders of which 5 are defective while shipment B contains 40 blenders of which 3 are defective. a. If 3 blenders are inspected at random (without replacement) from shipment A, what is the probability of obtaining at least 1 defective. b. Suppose a shipment is selected at random and one defective was found out of 2 blenders inspected. Find the probability that the shipment inspected was A.
