Question: 1. In Problem, you are told that the first two draws are white balls. Find the probability that the third is also a white ball.
Problem: An urn contains 4 white balls and 7 black balls. An experiment is performed in which 3 balls are drawn out in succession without replacing any. List all possible outcomes and as- sign probabilities to each.
2. An urn contains 4 red balls, 7 green balls, and 5 white balls. Another urn contains 5 red balls, 9 green balls, and 2 white balls. One ball is drawn from each urn. What is the proba-bility that both balls will be of the same color?
