Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the probability of choosing a blue marble, we need to find the total number of blue marbles and then divide by the total number of marbles in the bag.

The total number of blue marbles in the bag is 7. The total number of marbles in the bag is 3 (red marbles) + 7 (blue marbles) + 2 (green marbles) = 12.

Therefore, the probability of choosing a blue marble is 7/12.
