Jeremy and Noor are playing a game where they each draw a marble from a bag, and whoever draws the marble worth the most points wins. Red marbles are worth 1 point, green marbles are worth 2 points, blue marbles are worth 3 points, and white marbles are worth 10 points. There are 4 of each type of marble in the bag. Jeremy draws a blue marble from the bag and does not replace it.

Part A: If Noor draws a marble next, what is the expected value of Noor’s marble? Show your work.

Part B: Does this mean that Noor is more likely to win than to lose? Explain your answer.

    = ∑ x P(x)
