Jim Green does some math stuff about buying more than one card.

Written by Jim Green

Buying just one card in any game you play gives you the best theoretical return on your money.

This was a surprise when I first discovered the maths too.

Basically, buying one ticket when there are 99 other tickets gives you a 1/100 chance of winning. Your Expected Value (prize*probability of winning)-entry fee is 1-1=0

Buying two tickets when there are 99 other tickets gives you a 2/101 chance of winning 101. Your Expected Value is 101*(2/101) - 2 = -0.01
