InverseNormal( <Mean>, <Standard Deviation>, <Probability> )
Calculates the function \mathrm{\mathsf{ \Phi^{-1}(P) \cdot \sigma + \mu }} with given probability P, mean μ and standard deviation σ, where \mathrm{\mathsf{ \Phi^{-1} }} is the inverse of the cumulative distribution function Φ for N(0,1).
Note: Returns the x-coordinate with the given probability to the left under the normal distribution curve.
