You can put this solution on YOUR website! there is a test with 10 questions. All questions are independent from each other. if you are a good studen, for each question there is 80% chance that you will asnwer correctly. what is the probability that you will answer less than 6 correct
-----------------------------
Binomial Problem with n = 10 and p = 0.80
------------------------
P(0<= x <=5) = binomcdf(10,0.8,5) = 0.0328
