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

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.

It is 0.0033
.237 or about 24 %
Assuming you reply each answer randomly, your probability is (1/2)10 = 1/1024 (about 0.1%). Of course, if you have at least some idea about some of the questions, your chances improve (you will have to guess on less questions).
Assuming the questions are answered at random, the probability is 0.000009, approx.
64/256
That depends on how many questions there are, how many choices are listed for each question, and whether any obviously-stupid answers are included among the choices. If any of those factors changes, then the probability changes. One thing we can guarantee, however, even without knowing any of these factors: If you have studied the subject and know the material, then your probability of getting correct answers increases dramatically.
If it is a T/F test; probability correct for each question is 0.5. Since there are 4 questions, raise 0.5 to the 4th power; e.g. (0.5)4. So, probability all correct is 0.0625. If a 4 part multiple choice, P(correct) = .25 so raise .25 to the 4th power, or .003906.
