Ответ: 3)4 17+12-25=4

Answer 2

Minimum number of students who could have participated in both math and computer science olympiads

To find the minimum number of students who could have participated in both the math and computer science olympiads, we need to consider the overlapping number of students between the two olympiads.

According to the information provided, 17 out of 25 students participated in the math olympiad, and 12 students participated in the computer science olympiad.

To find the minimum number of students who could have participated in both olympiads, we need to find the maximum number of students who participated in both olympiads.

Since the total number of students in the class is not given, we cannot determine the exact number of students who participated in both olympiads. However, we can find the minimum number of students who could have participated in both olympiads by considering the maximum possible overlap.

If we assume that all 12 students who participated in the computer science olympiad also participated in the math olympiad, then the minimum number of students who could have participated in both olympiads is 12.

Therefore, the correct answer is 2) 12.
