Question

5. A bag contains 5 white, 6 red and 4 green balls. One ball is drawn at random. What is the
probability that the ball drawn is (i) green? (ii) white? (iii) non-red?​

Answer 1

Answer:

There are 15 total balls. The probability of drawing a green ball (assuming that balls are chosen at random) is 4/15; the probability of drawing a white ball is 5/15 or 1/3. The probability of drawing a non-red ball is 9/15 or 3/5. The probability of drawing a ball that is simultaneously "green, white and non-red" is zero, as there are no balls that are both green and white.
