A bag contains 7 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 choice from the following choices:
A) 2/3 B) 3/5 C) 1/5 D) 7/15 E) 8/15
Total number of balls = (7 + 5 + 6)=

18.   Therefore, n(S)= 18.   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) = (7/18 + 5/18) = 2/3.   2/3NSWER:2/3
