The value of (12 C 3) (the number of combinations of 12 items taken 3 at a time) can be calculated using the formula (nCr = \frac{n!}{r!(n-r)!}). For (12 C 3), this becomes:

[ 12 C 3 = \frac{12!}{3!(12-3)!} = \frac{12!}{3! \cdot 9!} = \frac{12 \times 11 \times 10}{3 \times 2 \times 1} = 220. ]

Thus, (12 C 3 = 220).
