(Data extracted from # Listen Learn Lead Global Research 2015, Accenture, 2015, p. 13.) Suppose that the survey was based on 500 respondents from each of the two generation groups.

c. What is the probability that a randomly selected respondent is likely to ask for a pay raise?

d. What is the probability that a randomly selected respondent is likely to ask for a pay raise and is a baby boomer?

e. Are the events "generation group" and "likely to ask for a pay raise" independent? Explain.
