Returns the individual term binomial distribution probability.
BINOMDIST(X; Trials; SP; C)
Returns a real number which is either a probability or a sum of probabilities defined by the binomial distribution. The value ranges from 0 to 1, i.e. [0,1].
X is a positive integer value or a reference to the cell containing that number which is the number of successes in a set of trials.
Trialsis a positive integer value or a reference to the cell containing that number which is the number of independent trials.
SP is a real number between 0 and 1(both inclusive) or a reference to the cell containing that value which is the probability of success on each trial.
C is a logical value that determines the form of the function. C = 0 or False to calculate the probability density function. It can be any other value like 1 or True to calculate the cumulative distribution function.
- If X and Trials are a non-integer value, then the function uses their floor value, i.e. they are truncated to an integer value.
- If X and Trials are less than zero then the function returns an error value. Also if X is greater than "Trials after truncation, then the function returns an error value.
- If SP is greater than 1 or less than 0, then the function returns an error value.
- The formula for BINOMDIST for probability density function (when C=0)is:
- The formula for BINOMDIST for the cumulative binomial distribution (when C=1) is:
