A box contains different-colored marbles. If P(blue) = 1, P(green) = 4, and P(blue and green) = 1, which statement is true?
The events are independent because P(blue). P(green) = P(blue and green).
The events are independent because P(blue). P(green) - P(blue and green).
The events are dependent because P(blue) • P(green) = P(blue and green).
The events are dependent because P(blue) • P(green) - P(blue and green).
