Chapter 5, Problem 9CQQ

In Exercises 6–10, use the following: Five American Airlines flights are randomly selected, and the table in the margin lists the probabilities for the number that arrive on time (based on data from the Department of Transportation). Assume that five flights are randomly selected.

x p(x)
0 0+
1 0.006
2 0.051
3 0.205
4 0.409
5 0.338

9. Is 0 an unusually low number of flights arriving on time?

Based on a survey, assume that 58% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when four consumers are randomly selected, exactly two of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting two consumers comfortable with drones followed by two consumers not comfortable, as in this calculation: (0.58)(0.58)(0.42)(0.42) = 0.0593? Choose the correct answer below. O A. The event that a consumer is comfortable with drones is not mutually exclusive with the event that a consumer is not comfortable with drones. O B. There are other arrangements consisting of two consumers who are comfortable and two who are not. The probabilities corresponding to those other arrangements should also be included in the result. O C. The calculation assumes that the first two consumers are comfortable with drones and the last two are not, but this arrangement is not possible.…
Assume that A, B and C are three independent events such that P (A) = 0.2, P (B) = 0.5 and P (C) = 0.1. Determine the probability that none of these three events will occur. Answer with the probability expressed as a percentage.
Based on a survey, assume that 33% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when six consumers are randomly selected, exactly three of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting three consumers comfortable with drones followed by three consumers not comfortable, as in this calculation: (0.33)(0.33)(0.33)(0.67)(0.67)(0.67) = 0.0108? Choose the correct answer below. A. The event that a consumer is comfortable with drones is not mutually exclusive with the event that a consumer is not comfortable with drones. B. The probability of the second consumer being comfortable with drones cannot be treated as being independent of the probability of the first consumer being comfortable with drones. O C. There are other arrangements consisting of three consumers who are comfortable and three who are not. The probabilities corresponding to those other…
