- Can someone help me with this math question? -
**Cindy**, Friday, November 30, 2012 at 1:45pmAn urn contains 8 pink and 7 red balls. 6 balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 6 balls drawn from the urn are pink? Round your answer to three decimal places.

**Damon**, Friday, November 30, 2012 at 1:54pmThere are 15 balls in the urn. Even as we pick our picks are returned to the urn so the probability of pink remains 8 out of 15 every time

so

(8/15)^6 = .015625 or .016
