<PRE><B>Question 187207</B>
500 raffle tickets are sold at $2 each. One grand prize of $100 and two consolation prizes of $50 will be awarded. Find Jake’s expectation (expected value) if he purchases one ticket. 
------------------------------------------
Random Number Values:........  -2......., 100...., 50....., 50
--------
Corresponding Probabilities.. (497/500), (1/500), (1/500), (1/500)
------------------------------
Expected winnings = (497/500)(-2) + (1/500)(100 + 50 + 50)
= -0.795 dollars = lose 80 cents
