Answer
$12$
Work Step by Step
Binomial Coefficient can be defined as:
$\displaystyle \binom{n}{k}=\dfrac{n!}{k!(n-k)!}$
Need to apply the formula to get the Binomial Coefficients.
Here, $n=12,k=1$
Therefore,
$\displaystyle \binom{12}{1}=\dfrac{12!}{1!(12-1)!}$
$=\dfrac{ 12 \cdot 11!}{11!}$ $\bf{(Simplify)}$
$=12$
