---------------------------
Note: Your description of the spinner indicates there is
no way to lose. Is that correct?
-----------------------------------------
E(x) = 2(1/2) + 10(1/4) + 15(1/4) + 0(-8)
---
E(x) = 1 + 2.5 + 3.75 + 0
---
E(x) = $7.25
----------------------
Fair Price: You should pay $7.25 to play the game.
But the truth is you cannot lose with the spinner
you have described.
