Question:medium

Out of 8 students in Section Alpha, 10 students in Section Beta and 12 students in Section Gamma, a teacher wants to create a team of three to represent the school in inter-school quiz competition. In how many ways the team can be formed such that all the members of the team are not from the same section ?

Show Hint

For problems with conditions like "not all from the same...", calculating the complementary event (all from the same) and subtracting it from the total unconstrained possibilities is usually much faster than calculating the constrained possibilities directly.
