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?

  • Math -

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

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