A survey was conducted that included several questions about how internet users feel about search engines and other websites collecting information about them and using this information either to shape search results or target advertising to them. In one question, participants were asked, "If a search engine kept track of what you search for, and then used that information to personalize your future search results, how would you feel about that?" Respondents could indicate either "Wouldnotbe okay with it because you feel it is an invasion of your privacy" or "Would beokaywith it, even if it means they are gathering information about you." Frequencies of responses by age group are summarized in the following table.

Age	Not Okay	Okay
18-29	0.1482	0.0607
30-49	0.2270	0.0910
50+	0.4005	0.0726

(a)What is the probability a survey respondent will say they arenot okaywith this practice? (b)Given a respondent is 30-49 years old, what is the probability the respondent will say they areokaywith this practice? (Round your answer to four decimal places.)(c)Given a respondent says they arenot okaywith this practice, what is the probability the respondent is 50+ years old? (Round your answer to four decimal places.)(d)Is the attitude about this practice independent of the age of the respondent? Why or why not?

No, because these events aren't mutually exclusive.Yes, becauseP(okay18-29) = 0. No, becauseP(okay | 30-49)P(okay).Yes, becauseP(okay | 30-49) =P(30-49 | okay).
