Answer to Question 1

T

Answer to Question 2

Even though the P(defective) changes from trial to trial, if the population is very large, the probabilities are very similar. For example, suppose the population has 10,000 items and 50 are defective. P(defective) on the first trial is 50/10,000 = 0.0050; if after 10 trials 45 defectives have been selected, P(defective) will be 45/9990 = 0.0045.
