you draw two marbles without replacement from a bag containing four green marbles and five black marbles the number of possible outcomes in the sample spaces

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
