A few centuries ago, probability was fashionably used in gambling to predict the outcomes. But in today world, probability has a wide range of advantages more than we could imagine.

Probability
Probability means chances of occurrence of events. It is a way of measuring uncertainty.
| Situations | Probability |
| We are getting old each day. | Certain to happen. |
| It may rain today. | It may or may not happen. |
| Sunrises from the West. | Impossible to happen. |
| Head will come if you toss a coin. | Possible to happen. |
| India was definitely going to win this match. | India may win or lose. |
Values of probability:
Probabilities can be expressed in terms of fractions, decimals or percent.
The values of probability range from \(0\) to \(1\).
If the particular event is certain to happen, then that probability will be \(1\).
If the event is cannot possibly occur, then the probability for that event is \(0\).
