A student randomly selects one marble from the group of marbles shown below and then tosses a balanced coin.

Question

3 red marbles
4 green marbles
2 blue marbles
A. What is the probability that the student will select a green marble and then toss a heads? Show all your work.

B. Use your answer in A to determine the likelihood that the student will select a green marble and then toss a heads. Explain your reasoning in complete sentences.

Answer 1

First, you have the probability of choosing a green ball which is 4/9. Then the probability of flipping heads is 1/2. So 4/9*1/2=4/18=2/9. These two probabilities get multiplied because it's a combined probability.
