Step-by-step explanation:
When we exclude 4 men then the total nunber of men from we have to select is left 16-4=12. Therefore 7 men are selected from 12 men in 12C7 ways.
Similarly, when 4 men are to be particularly included then 4 are already selected and three are to be selected from the rest 12 men. Therefore amser in this case is 12C3.
