for a possible new project about chance and astronomy i bought a Cosmic Chance $1 scratch-off Illinois Lotto ticket a week ago. i haven't scratched it off yet and am not sure if i need to/should yet. below is some research i've done on this scratch-off.

from the IL Lottery site

from the Book of Odds - this ticket has the same odds of a married male 15 - 44 using a condom during his last sexual encounter
