To find the total number of students, we use the principle of inclusion-exclusion. We add the students who speak Spanish (95) and French (32), then subtract those who speak both (13) to avoid double counting, and finally add those who speak neither (139). The calculation is 95 + 32 - 13 + 139 = 253.
