Question 575509: Student Life did a survey of students in which they asked if the person is
a part-time student or a full-time student. They also asked if the person
had voted in the most recent student election. The results follow:
Part-time Student Full-time Student Row Total
Voted 15 20 35
Did not vote 25 30 55
Column Total 40 50 90
If a student is selected at random from this group of 90 students, find
the probability that :
a) The student voted in the most recent election.
b) The student voted in the most recent election, given that the
student is a part-time student.
c) The student voted in the most recent election and the student
is a part-time student
