A student is making independent random guesses on a test. The probability the student guess correctly is 0.25 for each question. Assume that the guesses are independent. Find the probability of more than 10 correct in 40 guesses.
A student is making independent random guesses on a test. The probability the student guess correctly is 0.25 for each question. Assume that the guesses are independent. Find the probability of 2 or more are correct in 10 guesses.
A student is making independent random guesses on a test. The probability the student guess correctly is 0.4 for each question. Assume that the guesses are independent. Find the probability of at least 14 correct in 20 guesses. Round your answer to 3 decimal places.
A student is making independent random guesses on a test. The probability the student guesses correctly is 0.50 for each question. Assume that the guesses are independent. Find the probability of more than half of the questions correct in 14 guesses.
Find the probability of answering the first 3 questions on a test correctly if random guesses are made, assume that all the questions are multiple choice, each with 5 possible answers.
Assume that random guesses are made for six multiple choice questions on an SAT test, so that there are n equals 6 trials, each with probability of success (correct) given by p equals 0.25. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4.
A multiple choice test has 26 questions, and each has four possible answers, of which one is correct(i.e. the probability of guessing correctly is 0.25). If a student guesses on every question, a) find the probability of getting exactly 11 correct. b) Would it be unusual to guess correctly on exactly 11questions? Why?
5.2.17-T Question Help Assume that random guesses are made for seven multiple choice questions on an SAT test, so that there are n=7 trials, each with probability of success (correct) given by p=0.25. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4. P(X<4) =O (Round to four decimal places as needed.)
assume that random guesses are made for nine multiple choice
questions on an SAT test, do that there are n=9 trials, each with
probability of success (correct) given by p= 0.65.

Assume that random guesses are made for 12 multiple choice questions on a medical admissions test, so that there are n= 12 trials, each with a probability of success (correct) given by p= 0.25. Find the probability that the number x of correct answers is fewer than 6.
