The value of 12C3, also known as "12 choose 3" or the combination of 12 items taken 3 at a time, can be calculated using the formula nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items being chosen. Plugging in the values for n = 12 and r = 3, we get 12C3 = 12! / (3!(12-3)!) = 12! / (3!9!) = (12 x 11 x 10) / (3 x 2 x 1) = 220. Therefore, the value of 12C3 is 220.

How many combination of 12 are there?
do you mean how many combinations of any size? So we have 12 combinations of size 1 12C2=12x11/2 =66 of size 2 12C3 of size 3 and we keep going and need to add these. But there is a formula for adding all these. Think of the each number between 1 and 12, say 1, for any combination it is either in that combination of not in it. So we have 2^12 combinations. That is 4096
