PLEASE HELP!!!!!

Finding the expected value requires you to multiply the probability of an outcome by the value of that outcome and add all those values together.
A roulette wheel has the following probabilities.
red = 18/38
black = 18/38
green = 2/38
if the ball lands on red you win 100 dollars.
if the ball lands on green you win 85 dollars.
if the ball lands on black you will not win any money.
What is the expected value of your bet?
Round your answer to 2 decimal places. (i.e. "8.2369" -> "8.24")
