If you take two balls randomly out of a jar of colored balls, there is a 50% chance that the balls will both be red.
What is the total percentage of red balls in the jar?
i'm new at this, and i'm just going to guess at the solution. cuz after lookin at TomM's comments, i got really confused. i think it's 50%, is that right?
