see below

Step-by-step explanation:

6 red marbles, 4 yellow marbles, and 3 green marbles. = 13 marbles

a) P (red) = red / total = 6/13

b) P (not yellow) = not yellow/total = (13-4) / 13 = 9/13

c) P (red or green) = (red+green) / total = (6+3) / total = 9/13

d) P (not red or green) = P (yellow) = yellow/total = 4/13
