Question 1150251
.
<pre>

The expected value for your profit is  {{{1000/500 + (2*200)/500 + (14*10)/500}}} - 7 = {{{(1000 + 2*200 + 14*10)/500}}} - 7 = {{{1540/500}}} - 7 = 3.08 - 7 = -3.92 dollars per game.


In other words, be ready to lose $3.92 in average, if you play many times this game, buying every time 1 ticket from 500.
