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.
In order to answer, the number of questions on the test must be given.
The probability will depend on how much you know and the extent of guessing.
The answer depends on the number of choices available for each question.

Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question. Short Answer: 1/5 times 1/5=1/25
Multiple-choice questions are the most common format that incorporate closed-ended questions. They offer a list of predetermined options for responses, with students selecting the correct one.
a test strip that tests the acidity or alkalinity level of a liquid.
In order to answer, the number of questions on the test must be given.
Assuming the questions are answered at random, the probability is 0.000009, approx.
.237 or about 24 %
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.

Some advantages:you can explain in your own wordsyou can get partial credit if you don't get it exactly correctyou can get extra credit for a really great answeressay questions are usually worth more points on an examSome disadvantages:you have to study harder to really understand the materialthere are no hints like in a multiple-choice question
Depends on the questions, and how they are answered. T/F, multiple choice, matching, essay, etc. Could be randomly answering, making educated guesses, or applying some amount of knowledge on the subject. Each of these impacts the probability of supplying correct answers.
