Question
Chapter 9, Problem 9.1AYK
To determine
To explain the meaning of the statement “13 in 100000 American males have hemophilia.”
Expert Solution & Answer
Explanation of Solution
The given statement says that at any particular time period there are 13 males on an average out of 100000 having Hemophilia. It does means that when the researcher selects 100000 people out of them exactly 13 have the Hemophilia, it just an average per 100000 it might increase or decrease.

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?
