Essay; show all work. A community 5K run will award $50 to the winner. 60 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-gain values: 50-20 = 30 ; -20
Probabilities: 1/60 ; 59/60
-----------
E(gain)= 30(1/60)-20(59/60) = 1/2 - (59/3)= (3-59)/6 = -$9.33
----
A fair price would be 20-9.33 = $10.67
