In order to find out the probability, we need to know how many marbles we have in total. So lets sum them all:

4 red+ 3 blue + 7 green = 14 marbles.

The probability of we drawing a blue marble is equal to the number of blue marbles divided by the total sum of the marbles.

Since we have 3 blue marbles, the probability is 3/14
