Question

An integer is chosen from 1 to 50. What is the probability that it is divisible by 8?

Answer 1

The possible outcomes are 1, 2, 3, 4, 5................50.
Number of all possible outcomes = 50

Out of these, the numbers that are divisible by 8 = 8, 16, 24, 32, 40 and 48.
Number of favourable outcomes = 6
∴ P (getting a number that is divisible by 8) = $\frac{6}{50}=\frac{3}{25}$
