In a batch of 50 light bulbs, 5 are defective. Two are selected at random, without replacement, from the batch. Let A and B denote the events that the first and second light bulb selected is defective, respectively. 1. Are A and B independent events? Justify your answer. 2. If the sampling were done with replacement, would A and B be independent? Justify. Sample Space: A= B= ANB=
