Question
Certain means there’s a ________ chance than an event will happen.
- 99%
- 100%
- 98%
- 50%
Hint:
Probability of an event = Number of favourable outcome / Total number of 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 outcomes.
This means that there js 100 percent chance that the event will take place.
Hence, the correct option is (b).
Probability of a sure event is 1,for an possible event it is 0 and for all other events its value lies between 0 and 1.
