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)
[tex]=\text{ }\frac{5}{14}\text{ }\ast\frac{5}{14}\text{ }\ast\text{ }\frac{5}{14}\text{ }\ast\text{ }\frac{5}{14}[/tex][tex]=\frac{625}{38416}[/tex][tex]P\text{ = 0}.016[/tex]Probability that all 4 balls drawn are pink = 0.016
