Question 1

a.Suppose, there are four options in a MCQ.Multiple answers are not allowed. If you randomly pick an answer, what is the probability that your answer will be correct?

b.Now, suppose there are 10 such MCQS in a test. All questions are independent of each other, which mean one question is not related to other. Will this qualify as a binomial experiment?

c.Suppose, your cousin got married the day before quiz and therefore, you could not study at all for the test. You decided to answer all MCQ question randomly. What is the probability that you will get exactly 3 answers wrong out of 10 questions?
