Problem 2.191 a researcher receives 93 containers of oxygen. of those containers, 20 have oxygen that is not ionized and the rest are ionized. two samples are randomly selected, without replacement, from the lot. round your answers to three decimal places (e. g. 98.765). (a) what is the probability that the first one selected is not ionized? (b) what is the probability that the second one selected is not ionized given that the first one was ionized? (c) how does the answer in part (b) change if samples selected were replaced prior to the next selection? find the probability. (d) what is the probability that both are ionized?
