A fair coin is flipped seven times. What is the probability that heads occurs exactly 6 times if it is known that heads occurs at least four times? Two machines turn out all the products in a factory, with the first machine producing 35% of the product and the second 65%. The first machine produces defective products 7% of the time and the second machine 9% of the time. (a) What is the probability that a defective part is produced at this factory given that it was made on the first machine? (b) What is the probability that a defective part is produced at this factory? A door-to-door salesman expects to make a sale 22% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.48. If he makes no sale, the probability for a sale to the next customer stays at 0.22. What is the probability that he will make at least two sales with his first three visits?

For safety reasons, 5 different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills bank. Each of the 5 systems detects theft with a probability of 0.85 independently of the others. oxes. The bank, obviously, is interested in the probability that when a theft occurs, at least one of the 5 systems will detect it. What is the probability that when a theft occurs, at least one of the 5 systems will detect it? Your answer should be rounded to 4 decimal places.

A baseballer rikes out 47% of the batters he faces (that is, the probability that he strikes out any given batter correct is .47). (a) In a series of five games, he faces 180 batters. What is the probability that he strikes out exactly 81 batters? (b) In a month, he faces 630 batters. What is the probability that he strikes out 310 or more batters? Now, every day for eternity he faces 100 batters, and records the number he strikes out. (c) Find the mean μ, and the standard deviation σ, of the numbers (of batters he strikes out on different days) that he records.
