Answer 1

If a box contains 20 marbles and 10 are red and 5 are blue that only makes 15 marbles.... ?

Answer 2

Are there more colors?

Answer 3

that's really the point. 15 of the marbles are either red or blue...out of 20 total marbles.

Answer 4

If not then you should get the answer by adding 5/20 and 10/20 together... I'm not sure if that's correct but I think it is.

is it multiple choice?
