Raffle ticket odds, does buying say 10 out of 28,000, give you 1/2800 chance on every ticket or 1/28000?
In: Mathematics
Lots of confusion here. Some people are treating this like the typical dice rolling problem (if you roll 2 dice, your chance of getting at least one 6 is not double your chance with one dice).
I think the confusion lies in the question being a little ambiguous. When I think of a raffle, I think: 28,000 tickets are sold, 28,000 stubs get put in a hat, one is pulled out, and that is the winner. Done.
But did you mean that maybe fewer than 28,000 are sold, 28,000 stubs are put in a hat, and they keep pulling tickets out of a hat until they get one that was sold?
Or maybe they pull ten tickets stubs out and give a prize to each?
Also, what exactly do you mean by a 1/2800 chance on _every_ ticket? I don’t understand that.
