The probability is a very important branch of mathematics which in addition to statistics plays a vital role in maths, science, chemistry, psychology, geology, mining etc. Probability is a science of study of possibilities of happening an event. In probability, we usually calculate the chances of an event to be happening.
But what do we mean by an event ? First let us know what an experiment is. In probability theory, an experiment is a process which is supposed to have one or more results. For instance - Throwing a die, picking up a marble, flipping a coin are some simple experiments. An event is the set of all possible outcomes or results of such an experiment. There are different types of events - dependent events, independent events, mutually exclusive events etc. There is one more concept which we are going to discuss in this article in detail - simple event.
A simple event is an event that consists of exactly one outcome or we can say that, a simple event is the event of a single outcome. A probability value is assigned to each simple event using either relative frequency or personal probabilities. The notation P(E) is used to denote the probability of the event E to occur.
