How to Use BETA.DIST function in Google Sheets in 2020?

BETA.DIST functionThe BETA.DIST function returns the probability of a given value as defined by the beta distribution function.

Parts of a BETA.DIST function

BETA.DIST(value, alpha, beta, lower_bound, upper_bound)

Part
Description
Notes

value
The value at which to evaluate the probability function.

The given value must be a number from the given lower boundary to the given upper boundary.

alpha
The first shape parameter of the distribution.

The given alpha must be a positive number.

beta
The second shape parameter of the distribution.

The given beta must be a positive number.

lower_bound
The lower boundary of the function.

The default lower boundary is 0.

upper-bound
The upper boundary of the function.

The default upper boundary is 1.

Sample formulas

BETA.DIST(0.65, 1.234, 7, 0.5, 3)

BETA.DIST(0.42, 3, 8)

BETA.DIST(0.92, 0.5, 0.7)

BETA.DIST(A5, 0.5, 0.7, -1, 1)

Note

You can use BETADIST or BETA.DIST to perform this function.
