A bag contains 7 red marbles, 6 green marbles, 5 yellow marbles, and 2 orange marbles. Marbles are drawn twice with replacement. What is p(yellow and green)
The probability of drawing a yellow marble on the first draw is 5/20.
The probability of drawing a green marble on the second draw is 6/20.
Since we are drawing with replacement, the probability of both events happening is the product of their individual probabilities:
P(yellow and green) = (5/20) * (6/20) = 0.075 or 7.5%.
