Math Problem Statement

A survey of 1 comma 0911,091 adults was​ asked, "Do you feel overloaded with too much​ information?" Suppose that the results indicated that of 542542 ​males, 238238 answered yes. Of 549549 ​females, 275275 answered yes. Construct a contingency table to evaluate the probabilities. Complete parts​ (a) through​ (d). Question content area bottom Part 1 a. What is the probability that a respondent chosen at random indicates that​ he/she feels overloaded with too much​ information? 0.4700.470 ​(Round to three decimal places as​ needed.) Part 2 b. What is the probability that a respondent chosen at random is a female and indicates that​ he/she feels overloaded with too much​ information? enter your response here ​(Round to three decimal places as​ needed.)
