Normal[ <Mean μ>, <Standard Deviation σ>, x ]
Creates probability density function (pdf) of normal distribution.
Normal[ <Mean μ>, <Standard Deviation σ>, x, <Boolean Cumulative>]
If Cumulative is true, creates cumulative density function of normal distribution, otherwise creates pdf of normal distribution.
Normal[<Mean μ>, <Standard Deviation σ>, <Variable Value x>]
Calculates the function Φ((x – μ) / σ) where Φ is the probability density function for N(0,1).
Note: Returns the probability for a given x-coordinate value (or area under the normal distribution curve to the left of the given x-coordinate).
