My game based on the throw of a single dice

My game based on the throw of a single dice. The dice has 6 sides,and the winnings of each throw are the number that shows up on the dice. For example, if a player throws a 6, they get $6. The cost of each throw is $3.75. Each player can play the game multiple times, paying $3.75 for each throw of the dice.
 
The expected value is equal 1/6*(1 + 2+ 3 + 4 + 5 +6) = $3.50
