For the first marble chosen, the probability that the marble is green is 5/9.
After the first choice, since she didn't put it back, there are 8
marbles left, of which 2 are red. So the probability of the second one
being red is 2/8 = 1/4.
Since the question is asking the probability of BOTH events happening, you multiply the two probabilities.
So the answer is (5/9) * (1/4) = 5/36.
hope this helps

Answer:
1/3 of the pizza remains.
Step-by-step explanation:
Matthew eats 1/3 of 1/2 of the pizza, which is (1/3)*(1/2) = 1/6 of the pizza. The amount of pizza left is
1/2 - 1/6 = 3/6 - 1/6 = 2/6 = 1/3
1/3 of the pizza remains.
