1)A student enters a multiple-choice exam. Each question has 4 choices however, only 1 of the questions is correct. The probability that the student knows the answer to any given question is equal to the sum of the first 3 values in your dataset (my dataset is below)

[4 5 5 2 4 4 6 3 3 7 5 3 6 3 4 4 6 5 4 5 3 7 5 5 4 2 6 5 6 6]

divided by 30. If the student does not know the answer he chooses some answer at random. If he knows the answer he answers correctly.Given that the student answered correctly to a question what is the probability that he knew the answer? Use Bayesian rule in chapter 4.
