Calculation:
Consider the total number of students in the class to be 128.
Therefore, n(S)=128.
Compute the number of students who are on the honor roll and not going to college.
5648=4
Compute the number of students who are not on the honor roll and not going to college.
7656=20
Compute the total number of students not going to college.
n(E)=4+20=24
Compute the probability of event E by dividing the number of outcomes of an event by the number of outcomes of sample space.
P(E)=n(E)n(S)
=24128
=316
Therefore, the probability that a student is not going to college is 316.
