7) In an experiment, persons are asked to pick a number from 10 to 18, so that for each person the sample space is the set S = {10, 11, 12, 13, 14, 15, 16, 17, 18}. If A = {10, 11, 15, 16, 17}, B = {10, 12, 14}, and C = {14, 16, 18}, list the elements of the sample space comprising each of the following events. A) A B) B C C) A C D) A B

Solution

A) A\' = { 12 , 13 , 14 , 18}

B.) B U C = {10, 12 , 14 , 16 , 18}

C.) A C = {16}

D.) A B = {14}
