Answer 1

Randomly elected residents in a municipality had to answer questions about their life situation.
Among other things, we received the following information about the respondents:
ˆ 12% lack employment and are not students
ˆ 20% are students and lack employment
ˆ 7% are students and employees

therefore percentage of residents who are employed and not students = 100% - (12%+20%+7%) = 61%

(a) Compile the information in a Friend Chart
and calculate the percentage who has employment.

(b) What percentage of the students who are employed are students?

this question itself states that they are studentns who are employed so they obviously will be students

P(student | students who are employed) = 1

P.S. (please upvote if you find the answer satisfactory)
