Question

Choose the correct definition of (n/k) from below

Answer 1

Answer:C.  $\frac{n!}{k!(n-k)!}$

Step-by-step explanation:

We know that a combination is a collection of the items where the order doesn't matter. It is a way to calculate the total outcomes of an event where order of the outcomes does not matter. It is denoted by C(n,k) or (n,k) or (n/k).

The formula for the number of combinations of n things taken r at a time is given by :-

$C(n,k)=(n/k)=\frac{n!}{k!(n-k)!}$

Hence, C is the right option.
