Introduction
In our day to day life, we come across many uncertainties of events. We wake up in the morning and check the weather report. The statement could be 'there is 60% chance of rain today'. This statement infers that the chance of rain is more than that having a dry weather. We decide upon our breakfast from a statement that "corn flakes might reduce cholesterol". What is the chance of getting a flat tyre on the way to an important apartment? And so on. How probable an event is? We generally infer by repeated observation of such events in long term patterns. Probability is the branch of mathematics devoted to the study of such events. Random Experiment and Sample Space An experiment repeated under essentially homogeneous and similar conditions results in an outcome, which is unique or not unique but may be one of the several possible outcomes. When the result is unique then the experiment is called a deterministic experiment. Any experiment whose outcome cannot be predicted in advance, but is one of the set of possible outcomes, is called a random experiment. If we think an experiment as being performed repeatedly, each repetition is called a trial. We observe an outcome for each trial. The set of all possible outcomes of a random experiment is called the sample space, associated with the random experiment. Events An event is the outcome or a combination of outcomes of an experiment. In other words, an event is a s...
