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.

It is 0.0547
Probability of getting a perfect score in a three question true or false quiz?
If you answer randomly, 1 in 8.
A test consists of 15 true false questions what is the probability if the student guesses on all 15 questions?
What is the probability of what?Guessing them all correctly?Getting half of the correct?Getting them all wrong?PLEASE be specific with your questions if you want WikiAnswers to help.
On a ten question true-false quiz what is the probability of getting 70 percent or more correct by just guessing each answer?
Probability, P, of 70% or more correct (7 or more correct) is: P(7) + P(8) + P(9) + P(10). See the related link; N=10, P = 0.5, and K = 7, 8, 9, & 10. Therefore the probability is: .11719 + .04395 + .00977 + .00098 = .17189 or approximately 17.2% probability 7 or more correct.
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 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 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 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
