Answer 1

The mathematical sentence that can be used to calculate the probability of selecting a student who wants the option to keep studying online or is a boy is:

13/25 + 10/25 - 3/25

This accounts for the students who want to keep studying online, the students who are boys, and subtracts the overlap between the two groups.
