How many committees of 3 people are possible from a group of 12??

Answer 1

There are 220 possible committees of 3 people that can be formed from a group of 12.

This can be calculated using the combination formula:

C(n, k) = n! / (k!(n-k)!)

Where n is the total number of people (12) and k is the number of people in each committee (3).

Therefore, C(12,3) = 12! / (3!(12-3)!) = 12! / (3!9!) = (12*11*10) / (3*2*1) = 220.

So, there are 220 possible committees of 3 people that can be formed from a group of 12.
