Problem 5

(a) A typical customer service call lasts 8 minutes and 10 seconds, with a standard deviation of 1 minute and 5 seconds. If they receive 100 calls, how many of them will last longer than 10 minutes?

(b) There is a 92.2% chance of losing a game. What is the probability of losing at least 11 times if this game is played 12 times?

(c) Imagine that a telephone switching center receives calls based on Poisson distribution over a 15 minute period with = 5. At what probability will fewer than two calls be received?
