Consider the total number of students in the class to be 128.
Therefore, n(S)=128.
Compute the number of students going to college.
That is,
n(E)=48+56=104
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)
=104128
=1316
Therefore, the probability that a student is going to collége is 1316.
