BETAINV function
Returns the inverse of the cumulative beta probability density function for a specified beta distribution. That is, if probability = BETADIST(x,...), then BETAINV(probability,...) = x. The beta distribution can be used in project planning to model probable completion times given an expected completion time and variability.
Syntax
BETAINV(probability, alpha, beta, [A], [B])Square brackets indicate optional arguments.

Try BETAINV
Read the legacy BETAINV function name
=BETAINV(A2,B2,C2)BETAINV is the compatibility name corresponding to BETA.INV. For this Beta(2,2) distribution, 3*x^2-2*x^3 equals 0.15625 at x=0.25. The inverse returns the x-value for the supplied cumulative probability. Use the modern name when creating a new formula; the old spelling is useful when reading existing workbooks.
