Probability And Statistics Formulas

Probability (Event) = Favorable Outcomes/Total Outcomes = x/n. Probability is used to predict the outcomes for the tossing of coins, rolling of dice, or drawing a card from a pack of playing cards. The probability is classified into two types:. The analysis of events governed by probability is called statistics. View all of Khan Academy’s lessons and practice exercises on probability and statistics. The best example for understanding probability is flipping a coin: There are two possible outcomes—heads or tails.

Formulas. Formula 1: Factorial n! = n(n − 1)(n − 2). (1) n! = n ( n − 1) ( n − 2). ( 1) 0! = 1 0! = 1. Formula 2: Combinations (n r) = n! (n−r)!r! ( n r) = n! ( n − r)! r! Formula 3: Binomial Distribution X~B(n, p) X ~ B ( n, p) P(X = x) = (n x)pxqn−x P ( X = x) = ( n x) p x q n − x, for x = 0, 1, 2,., n x = 0, 1, 2,., n.
