In Class IX we learnt to find the probability on the basis of probability was developed by A.N. Kolmogorov

In earlier classes you have had a glimpse of probability when you performed Example 9 : Consider the frequency distribution table (Table 14.3

experiment then the conditional probability of the event E under the condition that the 13.1.9 Mean and Variance of a Random Variable.

In earlier Classes we have studied the probability as a (a) Find the conditional probability of obtaining a sum greater than 9

In Class IX we defined the experimental or empirical probability P(E) of anevent E as Number of trials in which the event happened P(E) = Total number of trialsThe empirical interpretation of probability can be applied to every event associatedwith an experiment which can be repeated a large number of times

In Class IX we learnt to find the probability on the basis of observations andcollected data This is called statistical approach of probability Both the theories have some serious difficulties For instance these theories cannot be applied to the activities/experiments which have infinite number of outcomes

This theory of probability is known as classical theory of probability In Class IX we learnt to find the probability on the basis of observations and collected data This is called statistical approach of probability Both the theories have some serious difficulties

The empirical probability P(E) of an event E happening is given by P(E) = Number of trials in which the event happened The total number of trials In this chapter we shall be finding the empirical probability though we will write ‘probability’ for convenience Let us consider some examples

In earlier Classes we have studied the probability as a measure of uncertainty of events in a random experiment We discussed the axiomatic approach formulated by Russian Mathematician A N Kolmogorov (1903-1987) and treated probability as a function of outcomes of the experiment
