Concept explainers
Use the information given in the previous exercise to determine the following probabilities.
- a. P(E and C or L)
- b. P(E|L)
- c. P(L|C)
6.102. Consider the following information about passengers on a cruise ship on vacation: 40% check work e-mail, 30% use a cell phone to stay connected to work, 25% bring a laptop with them on vacation, 23% both check work e-mail and use a cell phone to stay connected, and 51% neither check work e-mail nor use a cell phone to stay connected nor bring a laptop. In addition, 88% of those who bring a laptop also check work e-mail and 70% of those who use a cell phone to stay connected also bring a laptop. With
E = event that a traveler on vacation checks work e-mail
C = event that a traveler on vacation uses a cell phone to stay connected
L = event that a traveler on vacation brought a laptop
use the given information to determine the following probabilities. A Venn diagram may help.
- a. P(E)
- b. P(C)
- c. P(L)
- d. P(E and C)
