Suppose a shipment of 170 electronic components contains 3 defective components. to determine whether the shipment should be ac
cepted, a quality-control engineer randomly selects 3 of the components and tests them. if 1 or more of the components is defective, the shipment is rejected. what is the probability that the shipment is rejected?
If nCk represents the number of ways k parts can be chosen from a pool of n, the probability of interest is the complement of the probability of selecting all good parts. 1 - (167C3)/(170C3) = 42,085/804,440 ≈ 0.0523
