Exercise 5.1 Because all airline passengers do not show up for their reserved seat, an airline sells n= 125 tickets for a flight that holds only 120 passengers. The probability that a passenger does not show up is 0.10. Assume that the passengers behave independently. 1. Determine the probability mass function of the number of passengers (X) who show up for the flight. 2. Find the probability that the flight departs with empty seats. 3. Calculate the mean and variance of X.

In a study of intelligence, the time (in seconds) for a laboratory animal to reach a reward in a maze was found to have a probability density function f(t) = 8 t 2 , t ≥ 8 where 8 seconds is the minimum time to traverse the maze.

(b) Find the probability that an animal chosen at random takes more than 28 seconds given that it took less than 56 seconds.
The General Social Survey asked a sample of adults how many siblings (brothers and sisters) they had (X) and also how many children they had (Y). We show results for those who had no more than 4 children and no more than 4 siblings.

A local coffee shop in Greensboro sells coffee cups. Suppose that coffee cups are only one size and one type. The cup of coffee sells for $2.50 per cup. The daily demand for coffee (from that local shop in cups) can be expressed by the following probability mass function. x f(x) 15 0.06 20 0.22 25 0.37 30 0.25 35 0.05 45 0.05 The store manager estimates the cost of a cup of coffee to be $1.25 per cup. If she places an order at the beginning of the day for 30 units, How much time would she expect to sell? How much profit would she expected to make? How many cups would she expect to have left at the end of the day?

Amrita flips a biased coin repeatedly until she observes that both a head and a tail appear.The probability that a head will appear on a single flip is p, for 0 < p < 1. Find the probability mass function of N, the number of flips required to observe both a head and a tail. Hint: If N is the flip number that ends the experiment then that means that the N − 1 flips previous to flip N must all be the same as each other but different from the Nth flip. Also think about what the smallest value in the support of N must be. Finally remember that there are two cases: a sequence of tails followed by a head, or a sequence of head’s followed by a tail.
As in Exercises 6.14 and 6.24, let X and Y denote the proportions of time out of one workweek thatemployees I and II, respectively, actually spend performing their assigned tasks. The joint relativefrequency behavior of X and Y is modeled by the probability density functionf (x, y) =. x + y, 0 ≤ x ≤ 1, 0 ≤ y ≤ 10, elsewhere.a If employee I works half of the time, what is the mean time that employee II works?b If employee I works half of the time, what is the variance of the time that employee II works?
