Ok guys, it has been a while since I worked with probability so I might need some things cleaned up. Basically the scenerio is this: each ticket has a 1/20 chance of winning. Let's say you buy three tickets a year. ( you get a discount :P ) The chance of NOT winning is (19/20)^3 correct? And lets say you did this every year, does that mean that in say year five you would have a (19/20)^15 chance of NEVER winning in the five years?
