<PRE><B>Question 1023558</B>
the probability that the ticket will cost you 1 dollar is 1.


the probability that the ticket will win you 600 dollars * 1/1500 = 600/1500.


the probability that the ticket will win you 50 dollars is 50 * 5/1500 = 250/1500.


the probability that the ticket will win you 25 dollars is 25 * 20/1500 = 500/1500.


your expected value is -1 + 600/1500 + 250/1500 + 500/1500 = -.1.


the average loss for each dollar that is bet is equal to 10 cents.
