Question

a box contains 90 discs whcich are numbered from 1 to 90 if one disc is drawn at random from the box find prob that a no. is divisible by 5
​

Answer 1

Step-by-step explanation:

so in 1 to 90 nos divisible by 5 are 18.so the prob becomes 18/90

on solving its 1/5

Answer 2

YOUR ANSWER IS 1/5.

Given:-

A box that contains 90 discs which are numbered from 1 to 90 and one disc is drawn at random from the box.

To find:-

Probability that the no. of disk is divisible by 5.

Here

• Total number of disks = 90.

• Numbers from 1 to 90 which are divisible by 5 = 5,10,15,20........90

• Therefore total numbers which are divisible by 5 = 90/5 = 18.

Therefore prob. of the number is divisible by 5

= Total numbers divisible by 5/Total number of disks.

= 18/90

= 9/45

=1/5

So p(of the number divisible by 5) = 1/5.
