BETAINV
The BETAINV function returns the inverse of the given cumulative beta distribution probability value. All arguments are number values.
BETAINV(probability, alpha, beta, x-lower, x-upper)
probability: The probability associated with the distribution. probability must be greater than 0 and less than 1.
alpha: One of the shape parameters of the distribution. alpha must be greater than 0.
beta: One of the shape parameters of the distribution. beta must be greater than 0.
x-lower: An optional lower limit or bound for the specified x value or probability. x-lower must be less than or equal to probability. If x-lower is omitted, 0 is used.
x-upper: An optional upper limit or bound for the specified x value or probability. x-upper must be greater than or equal to probability. If x-upper is omitted, 1 is used.
