Algorithm for a probability curve I have a board game background and I like how 2d6 makes a sweet probability curve that peaks at 7.
I'd like an algorithm that lets me make a similar curve, where I can get random number X, where X can be between 0 and N, where it's most likely going to be around 80% of the value of N.
But my googling is landing me on wikipedia pages that are talking about math in an abstract way I don't understand.

Thanks in advance
