# Chance And Probability

##### Chance

In our day to day life, there are so many situations when we say that this is impossible, or this is possible, or this may or may not possible. So the situations which may or may not happen have the chance to happen.

##### Probability

Probability is the study of uncertainty The uncertainty of any doubtful situation is measured by means of Probability.

This tells us the chance of happening some outcomes from the total possible outcomes.

Example

If we throw a dice then what is the probability that we will get a 5?

Solution

Favourable outcome = 1 (there is only one possibility of getting 5)

Total no. of possible outcomes = 6 (total six numbers are there on a dice)

Probability of getting 5 = 1/6
