Before the start of a cricket match, the captains of the two teams under the supervision of the umpire, along with the two team caption tosses a coin to decide which team will bat first. who gets to bat first. The winner of thise toss decides whether to bat or ball first. Can we What are thecalculate chancesthe chances of each captain of winning the toss? Yes. Can we calculate the chances? The chance of each captain winning the toss is his or her probability.
Probability is the chance of an event occurring at least once. There are two types of probability. Experimental probability is determined from the results of an experiment. It is the actual outcome rather than the expected outcome.

Thus, 1, 2, 3, 4, 5 and 6 are the sample points in the sample space.
If wWhile rolling a dice, if we want the outcome to be 1 or 2, then 1 and 2 are the ‘Ffavourable Outcomes’outcomes’.
An outcome is called an ‘Event’event’. When If we get ‘2’ while rolling a dice, you get ‘2’ on rolling a dice, it is an event.
When the occurrence of an event is not possible, it is called an ‘Iimpossible Eevent’. When we roll an rolling an ordinary dice, the event of ‘7’ being an outcome is not possible. Thus, ‘7’ is an impossible event. The probability value of an impossible event is 0.
When the occurrence of an event is possible, it is called a ‘Ssure Eevent’. When we rolling a dice, the occurrence of 1, 2, 3, 4, 5 or 6 is a sure event. The probability value of a sure event is 1.
Exercise 1 Rohan’s society is organising a lottery draw. A lottery has to be drawn. There are 50 names chits in the a box containing the names of people who have purchased tickets for the lottery. from which the name of the winner will be drawn. Out of these, 20 chits contain the names of boys. There are 20 names are those of boys. When the lottery is drawn, wWhat is the probability that a girl’s name will be
