A bag contains 5 red and 3 green balls. Two balls are

Total number of balls = 5+3 = 8. Probability of drawing a red ball on the first draw = 5/8. Probability of drawing a red ball on the second draw, given that the first ball was red = 4/7. So, the probability of both balls being red = (5/8) * (4/7) = 5/14. Ans. a
