A bag contains five red marbles and ten white marbles. If a sample of three marbles contains at least one white marble, what is the probability that all the marbles in the sample areThe probability that at least one marble in a sample of three marbles is white is 0.9780(Round to four decimal places as needed.)The probability that all marbles in a sample of three marbles are white and at least one marble in the sample is white is 0.2637(Round to four decimal places as needed.)The probability that all the marbles in a sample of three marbles are white given that at least one of the marbles is white is 77(Round to four decimal places as needed.)

Suppose there is a finite population of size N that contains exactly K objects that has a specified…
