A class contains 25 boys and 13 girls, where 11 boys and 5 girls wear glasses. If one student was selected randomly from this class, find the probability that the student is a boy who does NOT wear glasses.
The probability of event occurring is equal to the number of favorable outcomes divided by the total number of possible outcomes in the sample space, . In this case, event is selecting a boy who does not wear glasses. Find the probability of event as follows:
Thus, the probability of selecting a boy who does not wear glasses is .
