Question

Holly is flipping a coin and pulling a marble from a bag. There are 4 white marbles, 2 blue marbles, and 5 green marbles, all of the same size, in the bag. What is the probability that the coin lands on heads and she pulls a green marble from the bag?

Answer 1

prob(head) = 1/2
prob(green) = 5/11

prob(head and green) = (1/2)(5/11) = 5/22

Answer 2
