On throwing a dice once, the probability of occurrence of a composite number is 1/2. Is the given statement true or false?

Solution:

Given a die is thrown once

We know that a die has 6 faces numbering from 1 to 6

Total outcomes are 6

The composite numbers are 4, 6

Required probability = 2/6 = 1/3

Hence, it is false.
