Answer

d. 1 Explanation 1. Identify the Combination Formula The combination formula is given by **{}_nC_r = \frac{n!}{r!(n-r)!}**. 2. Apply the Formula For {}_{8}C_{8}, substitute n = 8 and r = 8: {}_{8}C_{8} = \frac{8!}{8!(8-8)!} = \frac{8!}{8! \cdot 0!}. 3. Simplify the Expression Since 0! = 1, the expression simplifies to \frac{8!}{8! \cdot 1} = 1.

Explanation

1. Identify the Combination Formula<br /> The combination formula is given by **${}_nC_r = \frac{n!}{r!(n-r)!}$**.<br /><br />2. Apply the Formula<br /> For ${}_{8}C_{8}$, substitute $n = 8$ and $r = 8$: <br /> ${}_{8}C_{8} = \frac{8!}{8!(8-8)!} = \frac{8!}{8! \cdot 0!}$.<br /><br />3. Simplify the Expression<br /> Since $0! = 1$, the expression simplifies to $\frac{8!}{8! \cdot 1} = 1$.
