Answer 1

Hi

This is your answer.

The numbers from 1 to 100 which is divisible by 3 but not by 9 are 3,6,12,15,21,24,30,33,39,42,48,51,57,60,66,69,75,78,84,87,93,96,.

So total favourable outcome=22
Total outcome = 100

Probability that a number being picked from 1 to 100 is divisible by 3 but not by 9
= 22/100
=11/50 Ans
