You would like to evaluate the probability of success for testing a batch of n processors. To start out, let’s assume that if there is a problem with the batch, exactly 1 out of the n processors are defective. You are willing to test only k of the processors (due to budget or times constraints). (a) How many ways are there of testing k out of n processors? (b) How many ways are there of testing k processors with the...
