RD Sharma Solutions Class 8 Chapter 26

The term probability is mainly used in our day to day conversation. It is the measure of the possibility of events to occur. There are many events which cannot be expected with overall certainty. The best way we can judge exactly how likely they are occurring is by using the idea of probability.

Probability generally ranges in between 0 to 1. If there is no chance of an event to occur, then the probability of happening will be 0. If there are chances of the certain event to occur, then its probability of happening will be 100% or 1.

For example: If we roll two dice, what is the probability that the sum of the two is even?

Here the event of occurring may be 0 or 1. The basic formula of probability is given as: Probability of event (A) = (No. of ways A can occur) / (Total no. of possible outcomes)

Let’s calculate using the formula. What is the probability of rolling a 4 when a die is rolled?

Sol: When a single die is rolled, No. of ways it can occur is 1 and Total no. of possible outcomes is 6. The probability of the event (A) = 1/6.
