Question

10. A bag contains one red ball, two black balls and three white balls. (i) A ball is drawn at random from the bag. What is the probability that the ball drawn is white? (ii) The first ball drawn is replaced and a second ball is drawn at random. What is the probability of drawing two balls of different colours? (iii) If instead, the first ball drawn is not replaced and a second ball is drawn at random, what is the probability of drawing two balls of the same colour?

Step 1

The probability of drawing a white ball in the first draw: There are 3 white balls and a total of 6 balls (1 red, 2 black, and 3 white). So the probability of drawing a white ball is the ratio of the number of white balls to the total number of balls. Probability Show more…
