A team of 12 men is to be formed out of n person. The number of times ...
Put C,D and E as one unit
∴ Total people to be selected = 10 = 9 ppl + one group of 3
Similarly total no ppl= n-3+1 = n-(C,D,E) + a group of 3 ppl [Note:Here 3 ppl are replaced by one group of 3 ppl ∴ there are counted as one and not 3]
∴
Selection:n-3+1 C10 = n-2C10
∴ Total people to be selected = 10 = 9 ppl + one group of 3
Similarly total no ppl= n-3+1 = n-(C,D,E) + a group of 3 ppl [Note:Here 3 ppl are replaced by one group of 3 ppl ∴ there are counted as one and not 3]
∴
Selection:n-3+1 C10 = n-2C10

A team of 12 men is to be formed out of n person. The number of times ...
Can be formed from n persons is given by the combination formula:
C(n,3) = n! / (3!(n-3)!)
To find the number of times 3 men can be formed from a team of 12, we need to substitute n = 12 in the above formula and simplify:
C(12,3) = 12! / (3!(12-3)!)
= 12! / (3!9!)
= (12x11x10)/(3x2x1)
= 220
Therefore, 3 men can be formed from a team of 12 in 220 different ways.
C(n,3) = n! / (3!(n-3)!)
