How do you write an answer to a probability question?
Probability questions are not all the same so there is not a single kind of answer: it depends on the nature of the question!
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 five questions correct on a 20 question multiple choice test?
The answer depends on the number of choices available for each question.

64/256

There are five questions on a quiz with four possible answers what is the probability you get 100 percent?
Probability of each question correct is 1/4 or 0.25. Since there are 5 questions, raise 0.25 to the 5th power or (0.25)5. So, probability all correct is 0.0009765.
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.
Why is it that you ask a question about something and you get an answer for something else that has nothing to do with the?
Sometimes people's questions are so badly worded people who give answers are not sure exactly what they are asking. This could lead to an incorrect answer. Sometimes people who answer questions don't read the question properly and give incorrect answers
