Question 22 • Common Core Algebra II - MA3111 B-IC

Black Marble Points

Answer

Since E(black) = 0.24 and E(red) = 0.16, Seth should choose to play black marbles.

E(red) will be twice that of E(black), so Seth should choose to play red marbles.

Since E(red) = E(black), it is a fair game, so it doesn’t matter which color Seth chooses.

Both options will lose points because there are two ways to lose points and only one way to gain points. He should choose neither color.
