A community 5k run will award $50 to the winner. 75 people enter the race, and they each pay an entry fee of $20. Assuming they are all equally likely to win, what is a fair price for the competition? Round to the nearest cent.
--------
Random "winning values":::::::: 30........-20
Corresponding probabilities::::1/75.......74/75
----
Expected "winnings" = (30 - 20*74)/75 = -19.33
----
Fair price would be 20-19.33 = $0.67
