Minimum number of tickets for a match
It is a hard (and often open) problem to calculate the minimum number of tickets one needs to purchase to guarantee that at least one of these tickets matches at least 2 numbers. In the 5-from-90 lotto, the minimum number of tickets that can guarantee a ticket with at least 2 matches is 100.[3]

(March 1, 2004) I revised the draft of the explanation of Lottery 6/49 to produce version 3. At this point I don't have much momentum on this project, but please offer your comments on the forum (I got none this last week except for one negative one). See my remarks on the forum. I will bring this up in class tonight.
