The Powerball is up to $337M. A lot of people will pay $2 for a ticket this week for a chance to dream about what they’d do with the grand prize of hundreds of millions. A quick scan of the powerball odds show the mathematical probability of picking the grand prize correctly is 1 in 292,201,338.

I suspect a lot of people dreaming about their potential windfall this week will overestimate what they are really up against. The problem is we don’t have any context for rationalizing large numbers.
