Answer:

Blue: 3/5

Red: 1/5

if the question is asking for the probability of if one marble you will pick out of bag is red OR blue, it will be 4/5

Step-by-step explanation:

add all the marbles together. 25 marbles.

so if there are 15 blue marbles, then there would be a 15 out of 25 chance you will get a blue marble. simplified is 3/5. same goes for the red marbles.
