Aye we just finished learning this!    The answer would be the favorable out some (how many blues) over the total outcomes (all marbles added together) 
So the answer would be 3/14 or 21%
first find how many marbles are in the bag :

4+3+7=14

because there are 3 blue marbles the probability is 3/14

hope this helped :)
