**Reiny**, Tuesday, July 24, 2012 at 5:46pmassume the grand prize is drawn first

prop of winning = 1/1000

expected value = 800(1/1000) = 80 cents

prob of winning the consolation prize

= 1/999 + 1/998 (I assume the tickets are not returned to the pot)

expected value for Jeremy

= (1/1000)(800) + 100(1/999) + 100(1/998)

= 1.00
