Question
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.
