Answer:
Correct choices are 2, 4 and 5
Explanation:
Jonathon chooses a marble from the bag without looking: it can be red (r) marble, (y) yellow marble or (g) green marble. Then without replacing chosen marble, he chooses a second marble from the bag without looking.
If the first marble was (r), then the second can be (y) or (g).
If the first marble was (y), then the second can be (r) or (g).
the first marble was (g), then the second can be (y) or (r).
There are 6 possible outcomes:
ry, rg, yr, yg, gy, gr.
