-0.0526
Step-by-step explanation:
Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).
Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is
and probability of failure is
. For a win, X takes value 35 and for a loss X takes value -1. So the model is,



The mean for one bet is 
X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
