Each ball also has a symbol on it - half of each color has a ! symbol on the ball, and half of each color has a $ on it. o If you draw a single ball, what is the probability the ball is green? o If you draw a single ball, what is the probability the ball is red, or has an ! symbol? o If you draw 5 balls from the barrel without replacement, what is the probability they are all blue? o If you draw 3 balls from the barrel WITH replacement, what is the probability that each ball you draw has a $ on it? .
