Probability (10)An integer is chosen at random between 1 and 100. Find the probability that it is :
- divisible by 8.
- not divisible by 8
Answer
Total number of outcomes = 98
i. Favourable outcomes are 8, 16, 24, ..., 96 i.e., 12
Prob (integer is divisible by 8) = 12/98 or 6/49
ii. Prob (integer is not divisible by 8) = 1 - 6/49
= 43/49
