Question 316694
<font face="Garamond" size="+2">


First, how much would it cost to buy all of the tickets?  1000 X 1 = $1000.


How much would you win if you won all of the prizes?  400 + 2*75 + 10*20 = 400 + 300 + 200 = 900.


900 divided by 1000 is 0.9 and 0.9 times $1 is 90 cents. Your expected winnings per ticket are 90 cents.  In other words it costs you 1 dollar to win 90 cents. Don't play unless the proceed go for what you consider to be a good cause and you don't mind donating some of your money to that cause.
