Probability And Statistics : when we study in secondary school education Andhra Pradesh about the approaches of studying the theory of Probability they are Statistics approach and the classical approach of finding probability. In statistics approach we find the probability of occurrence of an event by observing the repeated experiments and their frequency. Here we find the ratio of the frequency of the event to be observes to the total frequency of the event which has been observed. Let us consider an event of throwing a coin. The possible outcomes of this event are Head and Tail, called as H and T.
The probability of getting a head on a throw of a coin will be the ratio of frequency of getting a Head to the total outcomes. Here we have total outcomes = 2 and the frequency of getting a head in total outcomes is 1. SO the probability of getting a head = 1/2. Similarly we can find the probability of getting a tail is also 1/2. This method of finding the probability applies to the cards, dice, coins and other many simple games of chance. When we are diverted from these games of chance and consider the situations which are likely to occur like probability of people who will die before age of 60, probability of getting a rain this week. In such cases it is not possible to do simple enumeration of cases which are likely to occur.
In upcoming posts we will discuss about Types of events and Learn Pythagorean Theorem. Visit our website for information on Stem and Leaf Plot
