Hello,
I need to write a computer program in which I need to get random
numbers in a range, that follow an approximation of a bell curve. I
tell the program that the average is say 20 and also say that most of
values lie between 15 & 25.
The range of the values is between 0,100. I have been suggested that I
would need to look at beta distribution to generate such numbers but I
could not figure out how to do it.

I would be thankful to you if anyonce can provide any further input in
this regard

Thanks
Harish
