Answer:
6/15
Step-by-step explanation:
First we are going to need to add the total number of marbles.
2+3+4+6=15
So the denominator will be 15.
It asks us to find the probability of blue marbles so we put how many blue marbles there is inside of the bag.
There are six blue marbles.
So the probability is 6/15.
Or you could write it 6:15
Or percentage but that's no fun..
