After the first one selected is defective, there are 99 chips left in the lot with 19 chips that are defective. Thus, the probability that the second one selected is defective given that the first one was defective is (c) By Eq. 43. A number is selected at random from (1, 2, . , 100). Given that the number selected is divisible by 2, find the probability that it is divisible by 3 or 5. 29)1 . 44. , A,beeventsinasamplespaceS.
