(a) Identify the random variable. X- (b) Construct a probability distribution for this data. (c) Find the expected value. (d) If a person is charged $10 to select one bill from the box, is the game fair? Explain why or why not.

Explanation / Answer

1) a) Expected winnings in state A's lottery = 0 + 50x0.004 + 100x0.001 = $0.3

b) Expected winings in state B's lottery = 0 + 50x0.002+ 100x0.0015 + 500x0.0005

= $0.5

c) Lottery of state B. The expected winning is high for lottery B and hence, given an option, I would play state B's lottery
