Marble Games

Using some leftover marbles from an old game, you create a bag of 9 marbles: 6 blue, 2 green, and 1

red. The three games below all use this bag of marbles.

Two of the Marbles: Two marbles are drawn out of the bag without replacement. If two green marbles

are drawn, the player wins $18. If a red marble is drawn with either the first draw or the second draw,

the player loses $4.50 (the cost to play). Otherwise, the player breaks even.

Three of the Marbles: Three marbles are drawn out of the bag without replacement. If at most two blue

marbles are drawn, the player wins $7. Otherwise, the player loses $14 (the cost to play).

All of the Marbles: Three marbles are drawn out of the bag with replacement. If at least one red marble

is drawn, the player loses $2 (the cost to play). Otherwise, the player wins $70.
