73. In the brigade, there are 10 men and 8 women. In how many ways can the brigade elect a delegation consisting of 3 men and 2 women?
73. Three men can be chosen in $C_{10}^{3}=120$ ways. Two women can be chosen in $C_{8}^{2}=28$ ways. By the rule of product, we get $120 \cdot 28=3360$ ways to elect a delegation of the required composition.
