Main concepts of Probability in Class 12 Maths
In Mathematics Class 12, Chapter 13, we will discuss the important concept of conditional probability of an event that occurred in another event, which will be helpful in understanding Bayes theorem, probability multiplication rules, and freedom of events. We will also learn an important concept of a random variable and its probability distribution, and also the mean and variance of a probability distribution. Class 12 Mathematics Chapter 13, we will study about importance of discrete probability distribution and use it in binomial distribution. Throughout Chapter 13 of class 12 Maths, we will discuss experiments that are likely to result equally, unless otherwise noted.

Many experiments are bizarre in nature. For example, a tossed coin shows a ‘head’ or ‘tail’, a manufactured item may be ‘defective’ or ‘non-defective’, a question may be answered ‘yes’ or ‘no’, An egg is ‘hatched’ or ‘not hatched’, the decision is ‘yes’ or ‘no’, etc. In such cases, one of the outcomes is called ‘success’ and the other is ‘no success’ or ‘failure’. For example, when a coin flattens, if the presence of the head is considered a success, the presence of the tail is a failure.
Every time we bounce a coin or die or do some other experiment, we call it a test. If a coin is tossed, say, 4 times, the number of attempts is 4, each with two consequences, namely success or failure. The result of any test is independent of the result of any other test. In each of these tests, the probability of success or failure remains constant. These independent tests have only two results, usually referred to as “success or failure”, are called the Bernoulli test.
