Here you could see all the different relationships that can be obtained by my one formula RV Sigma ; g(x) Notice the value of " k " which is the area of RV Sigma from 0 to .851 which gives the equivalent area for 1 Std. of the normal curve. " k " is then divided by Sigma in order to obtain the normal probabilities.
