(a) Explanation Given: The coach has 6 good hitters and 8 poor hitters. Explanation: Consider that, to select 3 hitters with 2 good hitters and 1 poor hitter, 2 good hitters must be chosen out of 6 good hitters in C ( 6 , 2 ) ways and the 1 poor hitter must be chosen from 8 poor hitters in C ( 8 , 1 ) ways, therefore, the number of ways to select such group is: C ( 6 , 2 )</ (b) To determine The number of ways to select 3 hitters at random with 3 good hitters. (c) To determine The number of ways to select 3 hitters at random with at least 2 good hitters.
