**Question:**

In how many ways can one select a cricket team of eleven from 17 players in which only 5 persons can bowl if each cricket team of 11 must include exactly 4 bowlers?

**Solution:**

Out of 17 players, 11 need to be selected. There are 5 bowlers, of which four must be selected in the team. So, we have to choose 7 players from the remaining 12 players.

Required number of ways $={ }^{5} C_{4} \times{ }^{12} C_{7}=5 \times \frac{12 !}{7 ! 5 !}=5 \times 792=3960$
