11-77.

Find the expected value of a single spin by finding the product of the probability and the value for each region. Find the sum for all the regions.

P(6) · (6) + P(−8) · (−8) + P(0) · (0) + P(A) · (8) =

expected value

Use the same equation from part (a), but put a −4 in place of the 8 for the value of *A*.
