A bag contains 8 red balls, 5 green balls and 6 white balls. A ball is drawn at
random from the box. What is the probability that the ball drawn is either red or green?  Choose the correct option: A) 2/5 B) 3/5 C) 1/5 D) 13/19 E) 8/15
Total number of balls = (8 + 5 + 6)=

19.   Therefore, n(S)= 19.   Let E1 = event of drawing a red ball.   and E2 = event of drawing a green ball.   Then, E1 n E2 = f.   P (E1 n E2) = P(E1) + P(E2) = (4/19 + 5/19) = 13/19   ANSWER:13/19
