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
Solution
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.
