Probability is considered as a branch of mathematics that deals with uncertainty. It has been developed out of practical considerations and is used in taking decisions in almost every field. For example, while going out of house on cloudy day we have to take decision whether we should carry an umbrella or not. Such type of decision is taken by taking into consideration the probability of the occurrence of the event.
Let n be the total number of trials and m be the total number of trials in which the event has happened. The empirical probability P(E) of an event to occur is defined as:
