If I have done my internet searching correctly, this formula will find the probability (P) of a given value (x) of a distribution with a given mean (mean) and given Standard Deviation (StdDev). p[x] = Math.exp(-((x - mean) * (x - mean)) / (2 * StdDev * StdDev)) / (Math.sqrt(2 * Math.PI) * StdDev); Can anybody more mathematically headed then me turn that around to find find the value(x) of a given probability(P)? Is that what I want to do to randomly pick x values based on a distribution of a given mean and standard deviation? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-community/message.cfm/messageid:323186 Subscription: http://www.houseoffusion.com/groups/cf-community/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-community/unsubscribe.cfm
