Question 1158979
.
<pre>

Probability to win $750 is  {{{1/1000}}}.


Probability to win either of five prizes at $250 is {{{5/1000}}}.


Hence, the money expectation to win is  {{{750/1000 + (5*250)/1000}}} = {{{2000/1000}}}.


From it, you should subtract  $4 which you pay for the ticket, and then you get expected value of the game  


    {{{2000/1000 - 4}}} = - $2.00.


It is EXTREMELY unfair game.


Statistically, you lose $2.00 in each game.

Is everything clear to you ?
