I have a friend who plays the lottery by buying one line that gets played in several games. So if he buys $20 he plays one set of numbers for 20 games. I think he would have better chance at buying 20 different lines for one game. I am not good at the specific math behind the odds. Am I right in this assumption or is my friend?
I talked with a friend who explains it like this: If you have a standard six sided die and bet that you would either get a 1 or 2 your chances are 2/6. If you bet that in two rolls at least one will be a 1 your chances are 11/36. There are 36 possible outcomes and 11 outcomes where at least one die is a 1. So 1/6=33.3% which is better than 11/36=30.5%.
