Question

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

Answer 1

Answer:

Your answer is D

n!/k!(n-k)!

Answer 2

The combination helps us to find a number of ways. The correct definition that describes the combination$(\mathrm{n} / \mathrm{k})$ is

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

Combination

A combination helps us to find the number of ways something can be selected from a set. It is given by the formula,

${ }^{n} C_{r}=C(n, r)$

$=(n / r)=\frac{n !}{r !(n-r) !}$

Where $n$ is the total number of choices in the set, $r$ is the number of choices we want.

Given to us

$(\mathrm{n} / \mathrm{k})$

The correct definition that describes $(\mathrm{n} / \mathrm{k})$ using the combination formula $(n / k)=\frac{n !}{k !(n-k) !}$

Hence, the correct definition that describes the combination $(n / k)$ is $(n / k)=\frac{n !}{k !(n-k) !}$

Therefore, the correct answer is option D.$\frac{n !}{k !(n-k) !}$
