Aleksandr [31]

Using it's concept, it is found that the probability that the special ball is chosen is given by:

p = \frac{1}{C_{n,k}}

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The total number of outcomes is given by the combination of k balls from the set of n balls, given by:

C_{n,k} = \frac{n!}{k!(n - k)!}

One ball is special, hence the probability the special ball is chosen is given by:

p = \frac{1}{C_{n,k}}
