Question 1105839: A brand name has 60​% recognition rate. If the owner of the brand wants to verify that rate by beginning with a small sample of 15 randomly selected​ consumers, find the probability that exactly 9 of the 15 consumers recognize the brand name. Also find the probability that the number who recognize the brand name is not
9.

probability of 9 is 15C9*0.6^9*0.4^6=0.2066 for 9
not 9 is 1-0.2066=0.7934.
