there are two urns A and B, that contain black and white marbles. Urn a contains 3 white marbles and 2 black marbles. Urn b contains 24 white marbles and 16 black marbles. If your reach into one of the two urns at random and pull out a white marble, what is the probability that your reached into urn A. Please express your answer to nearest whole percent

Please find below the answer. Don't hesitate to give a "thumbs up" for the answer in case you're satisfied with the answer.
So, the probability that it is a white ball = (1/2)*(3/5)+ (1/2)*(24/40)
The probability that the white ball came from urn A i s:
= (1/2)*(3/5) / (1/2)*(3/5)+ (1/2)*(24/40)
= (.6)/ (.6+.6)
= 1/2
= .50
This is basically 50%

8. There are three urns. Urnl contains 2 white and 3 black marbles, Urn2 contains 3 white and 2 black marbles, and Urn3 contains 1 white and 4 black marbles. First, the urn is selected equally likely, than a ball is drawn from the urn. a) We know that a white marble is chosen.

A jar contains black and white marbles. There are four more black marbles than white marbles. Two marbles are drawn from the jar at random. If the probability that the two marbles are the same color is equal to the probability that the two marbles are different colors, how many marbles are in the bag?

1. A jar contains 3 black and 2 white marbles. We continue to draw marbles one at a time until two black marbles are drawn. If a white marble is drawn, the outcome is recorded, and the marble is put back in the jar before drawing the next marble. What is the probability that we will get exactly two black marbles in at most three tries? Do this problem using a tree diagram! (2 marks)
