B. Five bowls are labeled 1,2,3,4,5. Bowl i contains i white and 5 − i black ping pong balls, for i = 1,2,3,4,5. A bowl is randomly selected, and 2 ping pong balls are selected from that bowl at random without replacement. Both selected balls were white. What is the probability they were selected from bowl 1? 2? 3? 4? 5?

Bowl A contains three red and two white chips, and bowl B contains four red and three white chips. A chip is drawn at random from bowl A and transferred to bowl B. Compute the probability of then drawing a red chip from bowl B. Let P(A)=0.3P(A)=0.3 and P(B)=0.6P(B)=0.6. Find P(A∪B)P(A∪B) when AA and BB are indepdenent. Let P(A)=0.3P(A)=0.3 and P(B)=0.6P(B)=0.6. Find P(A|B)P(A|B) when AA and BB are mutually exclusive.

Bowl 1 contains 7 red and 3 white chips. Bowl 2 contains 4 red and 5 white chips. A chip is randomly selected from Bowl 1 and placed in Bowl 2, then two chips are drawn from Bowl 2 without replacement. Find the probability that both chips drawn from Bowl 2 are red.

Urn A contains four white balls and three black balls. Urn B contains six white balls and seven black balls. A ball is drawn from Urn A and then transferred to Urn B. A ball is then drawn from Urn B. What is the probability that the transferred ball was white given that the second ball drawn was white? (Round your answer to three decimal places.) I can't seem to figure this out! Please help! Thank you!

possibility tree One box contains two black balls (labeled B1 and B2) and one white ball. A second box contains one black ball and two white balls (labeled W1 and W2). Suppose the following experiment is performed: One of the two boxes is chosen at random. Next a ball is randomly chosen from the box. Then a second ball is chosen at random from the same box without replacing the first ball. a. Construct the possibility tree showing all possible...

Two boxes are labelled I and II. Box I contains 4 black balls and 6 white balls. Box II contains 2 black balls and 8 white balls. A player randomly selects one box and then randomly draws 2 balls without replacement from the selected box. 1) What is the probability of obtaining 2 black balls? 2) Given that 2 black balls are obtained, what is the probability that Box I is selected? 3) Suppose that 20 players conduct the game...

There are 2 boxes. The first box contains 2 white and 5 black balls. The second box contains 4 white and 7 black balls. A random box is chosen and from it a random ball is drawn. a) What is the probability that the ball is white? b) If the ball is known to be white, what is the probability that it came from the 1st box?
