A multiple-choice test has 6 questions. There are 4 choices for each question. A student who has not studied for the test decides to answer all questions randomly with a Probability of success = p =.25. Let X represent the number of correct answers out of six questions. (i) Use binomial distribution to complete the table (ii) Find the probability that the student will be successful in at least 4 questions. (iii) Find the probability that the student will be...

You are to take a multiple-choice exam consisting of 100 questions with five possible responses to each. Suppose that you have not studied and so must guess (select one of the five answers in a completely random fashion) on each question. Let r.v. X represent the number of correct responses on the exam. (a). Specify the probability distribution of X. (b. What is your expected number of correct responses? (c). What are the values of the variance and standard deviation...

A multiple-choice examination consists of 20 questions. Each question has five choices, labeled A, B, C, D and E. All data for that exam is stored in a file exam.txt. The first line of data contains the correct answers to the twenty questions in the first 20 consecutive (one after the other) character positions. For Example: BECDCBAADEBACBEDDBED Each subsequent line in the file contains the answers for a single candidate. Data on a line consists of a candidate number (an...

A multiple choice exam consists of 12 questions, each having 5 possible answers. To pass, you must answer at least 8 out of 12 questions correctly. What is the chance of this, if ; a. You go into the exam without knowing a thing, and have to resort to Pure guessing? b. You have studied enough so that on each question, 3 choices can be eliminated. But then you have to make a pure guess between the remaining 2 choices....
