The probability of an event can never be

A
equal to 0

B
equal to 1

C
greater than 1

D
less than 1

Solution

Probability of an event =

Probability is greater than 1 means the number of favourable outcomes is greater than the total number of outcomes. This is not possible.
For example, when a dice is rolled, then there can never be 7 favourable outcomes because a dice has only 6 faces.
Therefore, the probability of every event is less than 1.
Hence, option (3) is correct.
