Answer: Number of ways $=\dfrac{8!}{8!0!}\ or \ 1$

Step-by-step explanation:

When there is no replacement , we use combination to find the number of ways to choose things.

Number of ways to choose r things out of ( with out replacement) = $^nC_r=\dfrac{n!}{r!(n-r)!}$

The number of ways to choose 8 things = $^8C_8=\dfrac{8!}{8!(8-8)!}=\dfrac{1}{0!}=1 [\because 0!=1]$

Hence, Number of ways $=\dfrac{8!}{8!0!}\ or \ 1$
