You have a 4 percent chance of guessing both answers correctly assuming there is only one correct answer to each question and that you may only answer once per question.
There is 1 right answer out of 5 possible answers, so the probability of guessing it correctly is 1/5 or 20% or 0.2.
Probability questions are not all the same so there is not a single kind of answer: it depends on the nature of the 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.
Not sure what a mulitple choice qustion is but if it is anything like a multiple choice question, it is 1/5 or 20%. I strongly advise you to get a dictionary, learn to spell or use a spell checker.

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.

Yes I have asked about 80 questions (In guessing)
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.

You cannot. Probability is not a question or puzzle to be solved, it is a subject - a branch of mathematics. There are questions within the scope of the subject that may be solved.
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.
