The probability of an event that is sure to happen, is 1.
Solution:
The event that is sure to happen is called a certain event and probability of such an event is 1 as this event is bound to happen.

Probability of event E + Probability of event “not E” = 1.

The probability of an event that is certain to happen is 1. Such an event is called sure or certain event.

The probability of an event is greater than or equal to 0 and less than or equal to 1.

The sum of the probabilities of all the elementary events of an experiment is 1.

The probability of an event that cannot happen is 0. Such an event is called impossible event.
