An urn contains 5 red, 6 blue, and 8 green balls. If a set of 3 balls is randomly selected, what is the probability that each of the balls will be (a) of the same color? (b) of different colors? Repeat under the assumption that whenever a ball is selected, its color is noted and it is then replaced in the urn before the next selection. This is known as sampling with replacement.
Answer to relevant QuestionsTwo dice are thrown. Let E be the event that the sum of the dice is odd, let F be the event that at least one of the dice lands on 1, and let G be the event that the sum is 5. Describe the events EF, E ∪ F, FG, EFc, and ...A town contains 4 people who repair televisions. If 4 sets break down, what is the probability that exactly i of the repairers are called? Solve the problem for i = 1, 2, 3, 4. What assumptions are you making? Compute the probability that a bridge hand is void in at least one suit. Note that the answer is not (Why not?) Two fair dice are rolled. What is the conditional probability that at least one lands on 6 given that the dice land on different numbers? If two fair dice are rolled, what is the conditional probability that the first one lands on 6 given that the sum of the dice is i? Compute for all values of i between 2 and 12.
