Answer 2

Answer:

Step-by-step explanation:

Concept Introduction:

The concept of probability will be used to solve this problem.

Given Information:

The number has to be selected from $1,2,3,4.....,25$ .

To Find:

The probability that the selected number is a multiple of $5$ .

Solution:

Consider $E$ is the event of getting the multiple of $5$ upto $25$ .

The numbers which are the multiple of $5$ is $5,10,15,20,25$ .

The number of favorable outcomes $=5$.

The number of total outcomes are $=25$ .

So, $P(E)=\frac{No. of favorable outcomes}{No. of total outcomes}$

The probability is $P(E)=\frac{5}{25} = \frac{1}{5}$ .

The probability that the number selected is a multiple of $5$ is $\frac{1}{5}$ .
