50%
On a true or false quiz with a total of four questions what is the probability of getting all four questions correct given that the answers to the first two questions are correct?
you'd have a 50% chance of getting the 3rd and 4th question correct because you said the first 2 questions are already anwsered correctly :)
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%.
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
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.

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 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 getting 5 out of 6 True false questions correct?
The answer should depend on how well you know the topic! It also depends on whether you have enough intelligence to make at least some informed guesses.But assuming you do not have that basic intelligence and are still doing the questions by simply guessing, the probability is 0.0938
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.
