Answer:

P (not green) = 17/20

Step-by-step explanation:

Given the following number of marbles:

Green : 3

Yellow : 4

Blue : 5

Pink :8

Total number of marbles = 3 + 4 + 5 + 8 = 20 marbles

if we draw 1 marble at random from the bag, the probability that the marble IS green,

P(Green) = 3/20

The probability that the marble is NOT green is,

P(Not Green)

= 1 - P(Green)

= 1 - 3/20

= 17/20
