A munitions warehouse contains 50 bombs, of which 3 are defective (6%). A sample of 10 bombs is drawn and tested. What is the probability that the sample will contain at most 1 defective bomb? (Note: Binomial distribution probability can't be used in this case because the sample is not drawn from a very large population)
