I cannot figure out how to solve the following question-
A jar contains red, blue and yellow marbles. The # of red is 10 more than the yellow, and the blue is double the yellow. If the probability of choosing a yellow marble is 1/5 how many marbles are in the jar?
This is as far as I can go: r+10=y 2y=b
Please help...
