The BETA.DIST function returns the beta cumulative distribution.

BETA.DIST takes 4 required arguments and 2 optional arguments:

Syntax: BETA.DIST(x, alpha, beta, cumulative, [A], [B])

#1)
Using the BETA.DIST function:
#2)
The arguments for the BETA.DIST function are:
Argument Required? Description
x Required The value between A and B at which to evaluate the function.
alpha Required A parameter of the distribution.
beta Required A parameter of the distribution.
cumulative Required A logical value that determines the form of the function. If cumulative is TRUE, BETA.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.
A Optional A lower bound to the interval of x.
B Optional An upper bound to the interval of x.
#3)
A few more things:
If any argument is nonnumeric, BETA.DIST returns the #VALUE! error value.
If alpha ≤ 0 or beta ≤ 0, BETA.DIST returns the #NUM! error value.
If x < A, x > B, or A = B, BETA.DIST returns the #NUM! error value.
If you omit values for A and B, BETA.DIST uses the standard cumulative beta distribution, so that A = 0 and B = 1

Summary

The BETA.DIST function returns the beta cumulative distribution.
