use Bernoulli Trials (the binomial distribution) with n = 8 and p = 14/20 = 7/10
Mr. Johnson gives his class a list of 20 study questions from which he will select 8 to be answered on the final exam. If a student knows how to answer 14 of the 20 questions, what is the probability the student will be able to answer correctly:
a) all 8 questions
b) exactly 5 questions
c) at least 6 questions
explain your reasoning please
use Bernoulli Trials (the binomial distribution) with n = 8 and p = 14/20 = 7/10
