The Better Business Bureau reported that approximately 72.2% of consumer complaints in 2006 were settled.
If a random sample of five consumer complaints is selected, what is the probability that none was settled?
----
P(settled) = 0.722
P(not settled) = 0.278
---
P(5 not settled) = 0.278^5 = 0.001660
==========
