Function: binomialDistributionProbability()

binomialDistributionProbability(successes, trials, probability): number

Defined in: functions/binomialDistributionProbability.ts:17

Returns the probability of the binomial distribution.

Suppose a biased coin comes up heads with probability 0.3 when tossed. The probability of seeing exactly 4 heads in 6 tosses is binomialDistributionProbability(4, 6, 0.3).

Parameters​

successes​

number

The amount of successes. Must be an integer greater than or equal to 0 and less than or equal to trials.

trials​

number

The number of trials. Must be an integer greater than or equal to 0.

probability​

number

The probability of success. Must be a number from 0 to 1, inclusive. If you want to use a percentage, convert it to a decimal by dividing by 100 (e.g. 50% becomes 0.5).

Returns​

number

The probability.

Deprecated​

Use the binomProb() function instead.
