Answer
$56$
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, $n=8,k=3$
Therefore, $\displaystyle \binom{8}{3}=\dfrac{8!}{3!(8-3)!}$
$=\dfrac{8 \cdot 7 \cdot 6 \cdot 5!}{(3 \cdot 2 \cdot 1)(5!)}$
Simplify.
$=56$
