Answer:
0.9936 is the probability that the student will fail.
Step-by-step explanation:
We are given the following information:
We treat adult guessing correct answer as a success.
P(guess correct answer) = 0.2
Then the number of correct guesses follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 10
The student needs atleast 6 correct answer to pass the test. We have to calculate the probability that the student will fail.
We have to evaluate:
0.9936 is the probability that the student will fail.
