Answer:

11/15 red, 4/15 blue

Step-by-step explanation:

There are 15 marbles in all so that is the denominator.

The numerator is the number of marbles for each color.

So...

11 red marbles / 15 total marbles

4 blue marbles / 15 total marbles

It depends because if you shake the bag it will be either red or blue but if you don’t and you pick from the top it will be blue but if you pick from the bottom of the bag then it will be red but the most likely the red color marble will be chosen.
