An urn contains 8 black and;

6 pink balls.

5 balls are randomly drawn from the urn in succession, with replacement.

What is the probability that all the 5 balls drawn from the urn are pink?

  • The probability of drawing a pink ball in the first draw is 6/14
  • The probability of drawing a pink ball in the second draw is 6/14
  • The probability of drawing a pink ball in the third draw is 6/14
  • The probability of drawing a pink ball in the fourth draw is 6/14
  • The probability of drawing a pink ball in the fifth draw is 6/14

The probability that all the 5 balls drawn is pink is 5 Ă— 6/14 = 30/14 = 2.143 (rounded off to 3 decimal places)
