We'll assume that there is an equal probability of any position on the wheel, so a
chance for any given number.
We must take the probability of getting a 27, then the probability of getting a 15, and multiply them together to find the chances that they both happen in a row.

C. Use the formula for area of a triangle 1/2(Base * Height). Using that we see that we have 1/2(a*b) + 1/2(c*c) + 1/2(a*b). Cleaning this up we get 1/2(2ab+c^2)
First, add or subtract all variables
y2 + 4y - 16y + 3y = -7y
-7y + 2 is your answer
