Question

A dealer sells leagues in packages of 100 and guarantees that only 10% are defective. A consumer reviews each package he buys, extracting 10 leagues without replacement. If none of the 10 is defective, please accept the package; otherwise it rejects it. Find the probability that it will reject a packet.

Answer 1

Probability of being defective is 0.10

Total samples selected are 10

Probability of non rejecting will be equal to probability of selecting 10 samples with no defective.

Now probability of rejecting will be equal to probability of selecting 10 samples with at least one defective.
