Given:

Number of white balls = 9

Number of pink balls = 5

Total number of balls = 9 + 5 = 14 balls

4 balls are drawn randomly with replacement

To find the probability that all 4 balls are pink, we have:

P(pink) * P(pink) * P(pink) * P(Pink)


=\text{ }(5)/(14)\text{ }\ast(5)/(14)\text{ }\ast\text{ }(5)/(14)\text{ }\ast\text{ }(5)/(14)
=(625)/(38416)
P\text{ = 0}.016

Probability that all 4 balls drawn are pink = 0.016
