Question

The probability of getting a prime number is the same as that of a composite number in a throw of a dice.

Options

• True

• False

Answer 1

This statement is False.

Explanation:

Prime numbers on a dice are 2, 3 and 5

⇒ Number of prime numbers on a dice = 3

⇒ Number of favourable outcomes for prime numbers = 3

Composite numbers on a dice are 4 and 4

⇒ Number of composite numbers on a dice = 2

⇒ Number of favourable outcomes for composite numbers = 2

Since the number of outcomes differs, therefore probability would differ too.
