Re: What are the odds of this numbers game?
How about this play: enter 100 times:
0000
0001
0002
...
0099
The first two digits, of course, could be anything.
1 in 100 you win $4k
9 in 100 you win $500
all other times you win $50
So take $50 off of all the prizes and call the cost of the play $45. +$40 EV from trifecta ($450 * 9%) and +$40 EV from quads, total EV of this play is -$45 + 40.5 + 39.5 = +$35.
You could do this every week!
How does this work for the house? Obviously you run the game until someone hits quads then take the money and run. I think your instincts might be right on Stan.
