Question

A random number is drawn between 1 - 100. Find P( multiple of 5 ).

Answer 1

0.2 or 20%

Explanation:

-Probability is the chance taking place and is calculated as the number of times that event occurs divided =by the total number of events.

-The are 20 multiples of 5 between 1 and 100:

`5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100`

#Given that there are 100 events and 20 multiples of 5, the probability can be calculated as follows:

`P(multiple\ of \ 5)=(Multiples \ of \ 5)/(Number \ of \ events)\\\\=(20)/(100)\\\\=0.2 \ or \ 20\%`

Hence, the probability of multiples of 5 between 1 and 100 is 0.2 or 20%
