If the 25 question test was true or false what is the probability that you can guess and get all correct perfect paper?
The probability is (1/2)25 = 1/33554432 = 0.00000003, approx
Students are required to answer 2 True of False questions and 1 multiple choice questions with 4 responses If the answers are all guesses what is the probability of getting all 3 questions correct?
The probability of correct true & false question is 1/2 and the probability correct multiple choice (four answer) question is 1/4. We want the probability of correct, correct, and correct. Therefore the probability all 3 questions correct is 1/2 * 1/2 * 1/4 = 1/16.
The probability of guessing and getting this question right is 1 out of 2. True of False?
True. When there are only two answers, so guessing should give you a 50% or 1 out of 2 chance of getting the right answer.
On an eight question true false quiz a student guesses each answer What is the probability that he gets at least One of the answers correct?
The probability of getting at least 1 answer correct = 1 - Probability of getting all answers correct.So in your case it for be P(at least 1 answer correct) = 1 - 1/256where 256 is your sample space, |S| = 2^8.
What is the probability of randomly guessing at least 8 questions correct on a 10 question true-or-false quiz?
It is 0.0547
What is the probability of getting a perfect score in a three-question true or false quiz?
The probability of getting a perfect score in a three-question true or false quiz is 100% if you studied and retained the subject matter and the questions addressed that subject. If, however, you did not study, and you made pure guesses without any bias towards an answer partially based in your (now rather poor) knowledge, then the probability of getting any one question correct is 50%, so the probability of getting all three questions correct is 50% to the third power, or 12.5%.
If the 25 question test was true or false what is the probability that you can guess and get all correct perfect paper?

What is the probability of answering a 9 question true false test correctly if you randomly guess?
The probability of getting the first answer correct is 1/2 The probability of getting the first two correct is 1/2 * 1/2 = 1/(22) The probability of getting all 9 correct is 1/(29) = 1/512 which is just under 0.2%
What is the probability of guessing the correct answer to a true or false question?
50%
What is the probability of getting a question right simple by guessing?
That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.
What is the probability that a person taking a 4 question true false test will get a hundred flipping a coin?
.5 chance of getting each question right.4 questions.5^4= .0625

Jack is taking a four item true false test He has no knowledge about the subject of the test and decides to flip a coin to answer the items What is the probability that he receives a perfect score?
The probability that he receives a perfect score is .5*.5*.5*.5 = 0.0625.
What is the probability of getting 25 out of 50 correct on a true false quiz if you guess on all the questions?

What are the two major reasons why psychology researchers do not involve probability sample?
Psychology researches do use probability samples, so the question is based on false premises.
