Q78 of 116 Page 42

In question, state whether the statements are true (T) or false (F).

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

False

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.


Hence, the statement is false.
