I think this is the wrong approach to playing the lottery. What I'd rather do is increase my odds of winning $100,000 to $2 million. I wouldn't even know what to do with $300 million, but a smaller jackpot would be a great financial cushion that wouldn't change my lifestyle very much.
He has a better chance of dying in an accident on his trip to and from the store to buy his tickets than he does of winning the jackpot.
