An integer is chosen at random between 1 and 100. Find the probability that it is (i) divisible by 8 (ii) not divisible by 8

Text Solution

Verified by Experts

The correct Answer is:
Total outcomes between 1 and 100 = 98
Nos. divisible by 8 = 8, 16, 24, ...., 96 favourable cases = 12
Required probability `=(12)/(98)=(6)/(49)`
(ii) Probability (integer is not divisible by 8) `=1-(6)/(49)=(43)/(49)`
