Probability A word which can also be used in the place of ‘Probability’ is ‘Chance’. We all are well aware of the word ‘chance’. We use it in our daily life. Whatever we do, whatever we observe, there is always a chance that this is going to happen or not. When we want to find out the value of this chance in a quantitative form, at that point of time we use ‘Probability’ at the place of ‘Chance’. Some basic terms related to probability: Experiment: Whatever we do, is called experiment. Outcome: Whatever is the result of the experiment is known as the outcome. Favourable Outcome: The outcome in which we are interested is known as favorable outcome. Total possible outcomes:  All possibilities related to the result of experiment. If one is aware with all the basic terms of probability, then the probability of any event / experiment can be found out by dividing the favourable outcome by total possible outcomes. For example: Suppose we have a pack of cards and we want to pick...
