Question 527694: Can please somebody help me to solve this? "Can you tell the difference between Coke and Pepsi in a blind taste test? most people say they can and have a preference for one brand or the other. however research suggests that people can correctly identify a sample of one of these prodcuts only about 60% of the time. Suppose we decide to investigate this question and select a sample of 15 college students.

Question: what is the probability at least 10 of the students will correctly identify Coke or Pepsi?

----------------------
Binomial Problem with n = 15 and p(correct) = 0.6
---
P(10<= x <=15) = 1 - P(0<= x <=9)
---
= 1 - 0.5932 = 0.4032
