The odds in favour of me getting a question right on a multiple choice driving test...
The odds in favour of me getting a question right on a multiple choice driving test is 2:3. I need to get at least two out of four questions correct ( use cases to show) on the driving test to pass. If I got the first question wrong, what is the probability that I will pass the test? Assume that the questions are independent events.

1. A simple model assumes that the probability of me getting a mental arithmetic question correct is dependent on whether or not I got the previous question correct. Suppose that under this nodel if I get a question correct then there is a 80% chance that will get the next olue still correct, whereas if I get a question wrong there is a 60% chance that I will get the next question correct. Rn be the event that I get...

Please help me these problem in R-Code On a multiple-choice exam with **four** possible answers for each of the five questions, what is the probability that a student would get four or more correct answers just by guessing? Hint: Use the fact that $P(E ∩ F) = P(E) · P(F)$ for two independant event (generalized for more than events) Getting one answer correct is independant of another. Also $$P(at least 4) = P(exactly 4) + P(exactly 5)$$, the last events...

A multiple choice test consists of 10 questions each with four choices (a,b,c,d) for each question. If a student must get at least 7 correct to pass the test, what is the probability that a student could pass the exam simply by guessing? Find your answer to 4 decimal places.

Assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=8 trials , each with probability of success (correct) given by p=.55 Find the probability that the number x of correct answers is fewer than 4 (Round to four decimal places as needed.) I did p(0)+p(1)+p(2)+p(3) and got .2603 , why is that wrong?

A 20 question multiple choice test with 5 possible answers on each question is given to a class and the instructor has promised that any student who gets more than half of the questions correct will pass the test. A student who has not attended the class nor read any of the assignments is hoping to pass the test purely on the basis of guesswork. What is the probability that the student will pass? (Hint: The probability that a guess...

suppose that carlos is taking a multiple-choice test where there are five answer choices for each question, and he randomly guesses on four questions. (a) What is the probability that he gets exactly three of those questions correct? (b) what is the probability that he gets at least one out of the four questions correct? (c) What is the probability that he gets none of the four questions correct?

You are taking a multiple choice test with 10 questions, with 4 different options per question. For each question, there’s only one correct answer. You haven’t studied for the test and you decide to choose the answers at random (each option equally likely). What is the probability that you get at least 7 of them right?
