5. Definition
Probability is a branch of mathematics that deals
with calculating the likelihood of a given event's
occurrence, which is expressed as a number
between 0 and 1
OR
When we calculate the prediction mathematically and
want to give some value is known as Probability.

7. Random Experiment
In random experiment we can not predict the
result in it, but we know that the what type of
thing it occupies,
7

8. There is 50 – 50
chances of the
heads or the
tails

9. Example 2
 Throwing a DIE is an example of Random Experiment because
we can not predict it’s result.

10. Sample Space
It is when we are performing the
random experiment and the result of
the random experiment is placed in a
set that set is known as the Sample
space.
For each Random experiment the
sample space can be calculated.

12. Sample space for throwing a COIN
When we are throwing a coin there is chance to
come heads or tails, throwing coin is Random
experiment and the Sample space for that
experiment will be
S = { H , T }
12

13. Sample space for throwing a DIE
 When we are throwing a DIE then what will be the out come we don’t know what
will be the outcome but we know that the possible outcome’s of is from 1 – 6
number can come
 Throwing a DIE is Random experiment and the sample space will be
 S = { 1 , 2 , 3 , 4 , 5 , 6 }
13

14. Sample space for throwing two coins
THE SAMPLE FOR THROWING TWO COINS WILL BE
S = { HH , HT , TH , TT }
14

15. SAMPLE POINT
Any one element of the sample space is
known as sample point.
15

16. EVENT
 Each element in a sample space is an Event
