Question

in a school 320 student 85 students are in the band 200 student are on teams and 60 student participate in both activities determine the probability of selecting that is involved in one activity and the probability of selecting student that is not involved on either activities

Answer 1

Result:

in a school 320 student 85 students are in the band 200 student are on teams and 60 student participate in both activities determine the probability of selecting that is involved in one activity and the probability of selecting student that is not involved on either activities

number of students in the band = 85

number of students in the team = 200

number of students in the team and band = 60

number of students in the team or band = 85+200-60=225

number of students involved in one activity = 225-60 =165

probability of selecting that is involved in one activity = 165/320

=0.5156

student that is not involved on either activities = 320-225 =95

probability of selecting student that is not involved on either activities = 95/320

=0.296875
