Suppose a quiz has 11 multiple choice questions. Each question has 4 answer choices. If a student takes the quiz and randomly guesses on every question Question 1 Find the probability thestudent gets between 3 and 8, exclusive, questions correct. Question 2 Find the probability the student gets more than 7 questions correct
This question is based on binomial probability distribution, where n = 11 and Probability of makng a correct answer is 0.25.
Since each question has only 1 correct answer out of 4 options So probability of making correct answer is 0.25.
The formula used to get the probability is given on white board.
We have to find the probability of getting more than 4 and less than 8 correc answers out of 11.
Now we have to calculate the probability that more ...
