5. Mohammad Abdullah is a student taking a statistics course. Unfortunately, he is not a good student. He does not read the textbooks, does not do homework, and regularly misses class. He intends to rely on luck to pass the next quiz in an online multiple choice exam. The quiz consists of 10 multiple-choice questions, each question is for 1 mark. Each question has five possible answers, only one of which is correct. Mohammad Abdullah plans to guess the answer to each question. (a) What is the probability that he gets no answers correct? (b) What is the probability that he gets two answers correct? (c) What is the probability that he gets at most three answers correct? (d) A mark is considered a failure if it is less than 50% (5 out of 10). Find the probability that Mohammad Abdullah fails the quiz.
g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…
