Assume that random guesses are made for 8 ​multiple-choice questions on a test with 2 choices for each​ question, so that there are n=8 ​trials, each with probability of success​ (correct) given by pequals=0.50 Find the probability of no correct answers.

Assume that random guesses are made for ninemultiple choice questions on an SAT​ test, so that there are n=9​trials, each with probability of success​ (correct) given by p=0.4Find the indicated probability for the number of correct answers.   Find the probability that the number x of correct answers is fewer than 4.

Assume that random guesses are made for nine multiple choice questions on an SAT​ test, so that there are n=9 ​trials, each with probability of success​ (correct) given by p=0.35. Find the indicated probability for the number of correct answers.   P(X<4) =

Assume that random guesses are made for 3 multiple-choice questions on a test with 2 choices for each​ question, so that there are n=3 trials, each with probability of success​ (correct) given by p=0.50. Find the probability of no correct answers.

A student is working on a homework assignment with 5 questions. Each question on the assignment has 3 possible choices, which the student chooses from at random. Assuming that the answers are independent of each other, what is the probability that the student answers all the questions correctly? Report your answer to the 4th decimal place, that is, 0.0025 instead of 0.003.
