A class contains 40 boys and 16 girls, where 10 boys and 7 girls wear glasses. If one student was selected randomly from this class, find the probability that the student is a boy who wears 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 wears glasses. Find the probability of event as follows:
Thus, the probability of selecting a boy who wears glasses is .
