ATQ, Total number of balls in the bag = 9+ 16 + 20 = 45 Probability of selecting 1 blue ball out of all the balls, P(E1) = (9/45) Probability of selecting 1 green ball out of all the balls, P(E2) = (20/45) The probability of drawing either blue ball or green ball = P(E1) + P(E2) = (9/45) + (20/45) = (29/45)
