# Certain event means there is a __ chance that an event will happen.

- 99%
- 100%
- 98%
- 50%

Hint:

### Probability of an event = Number of favourable outcome / Number of total outcomes

## The correct answer is: 100%

### Here, we need to find the probability of a certain event.

A certain event is an event which is sure to happen.

The probability of an event is 1 if the number of favourable outcome is equal to the number of total outcome.

This means that there is 100% chance that the event will take place.

Henec, the correct option is (b).

Probability of a sure event is 1 , for an impossible event it is 0 and for all other events its value lies between 0 and 1.
