Case 1: You choose both questions, so you have to choose 4 more from the 9 remaining. (9C4 ways)

Case 2: You choose neither. So you have to choose 6 questions from the 9 remaining. (9C6 ways)

Candidates have to choose 6 questions.

If they choose question 1 and 2, they have to choose 4 more from what's left.

If they don't choose question 1 and 2, then they have to choose 6 from what's left.
