Answer:

13/36

Step-by-step explanation:

red/blue OR red/green OR blue/green

(4/9 × 2/8) + (4/9 × 3/8) + ( 2/9 × 3/8)

Answer:.753

Step-by-step explanation:

Let Ps = probability both marbles are the same color. Let Pd = probability both marbles are a different color. Pd = 1 -Ps let Pb = probability both marbles are blue let Pr = probability both marbles are red. Let Pg = probability both marbles are green pb= 2/9 * 1/9 = 2/81 or= 4/9 * 3/9 = 12/81 pg=.3/9 * 2/9= 6/81 ps = Pb + Pr +Pg= 20/81 pd

Pd =1-Ps= 61/81 = .753
