The binomial distribution is used to represent the number of events that occurs within n independent trials. Possible values are integers from zero to n. Where equals.
It can be classified into various groups. Statistical data are the facts which are collected for the purpose of investigation. There are two types of statistical data:. As the primary data are collected by the user of the data, so it is more reliable and relevant. For example score of a cricket match noted from newspapers is secondary data. Above data can be written as. For example the above data can be grouped in following manner.
Conditional Probability. Permutations nPr for Multiple Subsets. Sample Size by Standard Deviation. Sample Size by Proportion. Population Variance Estimation. Population Variance. Standard Deviation.
Considering the Probability and Statistics importance in exams like JEE Main, there are about questions that are asked directly from each chapter.

Probability Formula: Probability formulas are useful for calculating the probability of an event to occur. Probability is the branch of Mathematics that deals with numerical descriptions of the chances of an event to occur. The probability of an event always lies between 0 and 1, where, 0 indicates an impossible event and 1 indicates a certain event. Suppose, the probability of occurrence of an event is x, then the probability that the event will not occur is denoted by 1-x.
