Answer:
Therefore, the probability is P=0.0084.
Step-by-step explanation:
We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.
Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.
We calculate the probability of getting exactly 6 correct answers.
n=9 and k=6.

Therefore, the probability is P=0.0084.
