    7/12

    Step-by-step explanation:

    To find the probability of drawing a blue marble you need to find how many marbles there are in total.

    So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.

    So 3 + 7 + 2 = 12

    There are 12 marbles in total so now you have to find how many blue marbles there are.

    There are 7 blue marbles out of 12 marbles.

    Now you have to put this as a fraction to see if it can be simplified.

    7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.
