An exam has three questions. You estimate your probability of getting the first question right is 0.7, your probability of getting the second question right is 0.6, and your probability of getting the third question right is 0.5. Let Y be a random variable that is the number of questions you get right on the exam. What is the distribution ofY?

Assume that the number of multiple-choice questions I get correct out of 100 follows a binomial distribution with me just guessing with an equal probability for each answer (A-D). Find the exact probability of me getting 25 or less correct under these assumptions. check if the CLT conditions are satisfied first, then find an approximate probability, assuming that the number of correct answers out of 100 follows a normal distribution.

Multiple-choice questions each have 3 possible answers, one of which is correct. Assume that you guess the answers to 5 such questions. Use the multiplication rule to find the probability that the first four guesses are wrong and the fifth is correct. That is, find P(WWWWC)P(WWWWC), where C denotes a correct answer and W denotes a wrong answer. (round answer to 4 decimal places) P(WWWWC)= What is the probability of getting exactly one correct answer when 5 guesses are made?...

Multiple-choice questions each have 3 possible answers, one of which is correct. Assume that you guess the answers to 4 such questions. Use the multiplication rule to find the probability that the first three guesses are wrong and the fourth is correct. That is, find P(WWWC)P(WWWC), where C denotes a correct answer and W denotes a wrong answer. (round answer to 2 decimal places) P(WWWC)=P(WWWC)= What is the probability of getting exactly one correct answer when 4 guesses are made?...
