On each trial, the event of interest either occurs or does not. WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a success, and rolling any …

WebSometimes, binomials are given as the sum of cubes, for example, x 3 + 27. In such cases, the following algebraic identity can be used to factorize the binomial: a 3 + b 3 = (a + b) (a 2 - ab + b 2 ). For example, let us factorize the binomial x 3 + 27. Here x 3 is the cube of x and 27 is the cube of 3.
