Chapter 8, Problem 8CRE
Lightning Deaths Based on the results given in Cumulative Review Exercise 6, assume that for a randomly selected lightning death, there is a 0.8 probability that the victim is a male.
- Find the probability that three random people killed by lightning strikes are all males.
- Find the probability that three random people killed by lightning strikes are all females.
- Find the probability that among three people killed by lightning strikes, at least one is a male.
- If five people killed by lightning strikes are randomly selected, find the probability that exactly three of them are males.
- A study involves random selection of different groups of 50 people killed by lightning strikes. For those groups, find the
mean and standard deviation for the numbers of male victims. - For the same groups described in part (e), would 46 be a significantly high number of males in a group? Explain.

59. At a certain gas station, 40% of the customers use regular gas (A1), 35% use plus gas (A2), and 25% use premium (A3). Of those customers using regular gas, only 30% fill their tanks (event B). Of those customers using plus, 60% fill their tanks, whereas of those using premium, 50% fill their tanks.a. What is the probability that the next customer will request plus gas and fill the tank (A2 B)?b. What is the probability that the next customer fills the tank?c. If the next customer fills the tank, what is the probability that regular gas is requested? Plus? Premium?
