Question 129088
If you bought all 1000 tickets, it would cost you $3000, and you would win all of the prizes, so you would get 1000 + 500 + 5(100) = $2000 back.  {{{2000/3000=2/3}}}, so for every $1 you wager, you have an expectation of $(2/3).  Buying two tickets costs you $6.  6 X 2/3 = 4, so your expectation for 2 tickets is $4.


Go to Las Vegas instead.  Slot machines pay out roughly $0.90 per $1.00.  You'll lose your money much more slowly.
