4. Suppose there are N multiple-choice questions in an examination. Each questionhas 4 choices. You have a probability of 0.6 of knowing the correct answer to aparticular question. If you do not know the answer, you pick one at random. Youranswer to different questions are independent of each other.(a) For a particular question, find the probability that you answer it correctly.(b) Suppose N = 3. Given that you have answered all questions correctly, what%Dis the probability that you only know the answer to exactly two questions?
