A delivery of 25 parts is evaluated for quality purposes according to the following scheme: A sample of size 5 is drawn (without replacement of drawn parts). If at least one part is faulty, then the delivery is rejected. If all 5 parts are o.k., then they are returned to the lot, and a sample of size 10 is randomly taken from the original 25 parts. The delivery is rejected if at least 1 part out of the 10 is faulty.
Determine the probabilities that a delivery is accepted on condition that (1) the delivery contains 2 defective parts,
(2) the delivery contains 4 defective parts.
