We have two bags containing marbles: • Bag A contains 4 blue, and 3 green marbles • Bag B contains 2 blue, 5 green, and 3 yellow marbles We perform this two step procedure. First, draw a marble from bag A uniformly at random. Then put this marble into bag B. Second, draw a marble from bag B uniformly at random. We keep this marble. What is the probability that the marble we keep is green?
A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. If a marble is selected at random, what is the probability of choosing a marble that is not blue? 7+2+1=10 There are two blue marblesSo is the probability 1/5?
First bag contains 7 blue marbles , 6 green marbles and another bag contains 2 blue marbles, 4 green marbles and 3 yellow marbles. We draw a random marble from first bag and and place it to the other bag. Then We draw a marble from the second bag randomly and keep this one. Calculate the probability that the marble we pick is green.

A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. If a marble is selected at random, what is the probability of choosing a marble that is not blue?I have seen so many different answers on this site to this question and am not sure. I thought it would be 7 red +1 green gives 8/10=4/5.Our choices for the answer is 4/5,1/5, 5/4, 8
