Hall of Fame
Categories : probability : lottery.p

There are n tickets in the lottery, k winners and m allowing you to
pick another ticket. The problem is to determine the probability of
winning the lottery when you start by picking 1 (one) ticket.

A lottery has N balls in all, and you as a player can choose m numbers
on each card, and the lottery authorities then choose n balls, define
L(N,n,m,k) as the minimum number of cards you must purchase to ensure
that at least one of your cards will have at least k numbers in common
with the balls chosen in the lottery.
