Abag contains 5 blue marbles, 6 red marbles, and 9 green marbles. two marbles are drawn at random, one at a time. what is the probability of selecting a green marble and then, without replacing it, a red marble?

A green marble 9/20 and a Red marble 6/20 or Red 3/10

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
