The Motor Vehicle Department has found that the probability of a person passing the test for a driver's license on the first try is 0.74. The probability that an individual who fails on the first test will pass on the second try is 0.83, and the probability that an individual who fails the first and second tests will pass the third time is 0.65. Find the probabilities that an individual will do the following a. P(Fail both the first and...

2. Number Cards: There are 25 people sitting around a table, and each person has two cards. One of the numbers 1, 2, 3, , 25 is written on each card, and each number occurs on exactly two cards. At a signal, each person passes one of her cards the one with the smaller number to her right-hand neighbor. Prove that, sooner or later, one of the players will have two cards with the same numbers. 3. Airplane: Imagine...

9. A father asks his sons to cut their backyard lawn. Since he does not specify which of his three sons is to do the job, each boy tosses an unbiased coin to determine the odd person, who must then cut the lawn. In the case that all three get heads or tails, they continue tossing until they reach a decision. What is the minimum number of tosses required to reach a decision with probability 0.957 10.
