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).

A test has 2 multiple choice questions each with 3 choices what is the probanility of guessing the correct answers to both questions?
The probability of getting both answers correct is one chance in nine (0.1111+). There are three possible answers for each question, so there is a 1/3 chance of getting the correct answer to one question. To get the correct answer for both questions, the chances are 1/3 x 1/3 or 1/9.
What is the probability of getting exactly 7 out of 12 multiple choice questions right if a student randomly guesses one of the five possible choices for each question?
It is 0.0033
What is probability of getting 20 multiple choice questions wrong in a row?
Let us say that for each question, there are n multiple choices. If this is true and false, then n=2. The chance of getting a right answer is 1/n and wrong answer (n-1)/n. I will define p as getting a wrong answer one time (p = (n-1)/n so the probability of 20 wrong answers is p20. Now for n = 4, p=0.75 and the chance of 20 wrong answers in a row is: (0.75)20= 0.0032 or 0.32%.
In a multiple choice test what is the probability of getting two answers correct?
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.
What is the probability of getting a multiple of 3?
The probability of getting a multiple of 3 depends on the total number of possible outcomes. For example, if you are rolling a fair six-sided die, there are two outcomes that are multiples of 3 (3 and 6), out of a total of six possible outcomes. Therefore, the probability of getting a multiple of 3 is 2/6 or 1/3.
Is it better to skip or guess a question in the SAT?
If you can recognize one or more of the possible answers on the SAT multiple choice as clearly NOT being correct, but you are unsure of the correct answer, it is better to guess than to skip the question.
What is the probability of getting all five answers correct if i have five multiple choice questions with four possible answers determine the number of possible answers?
The probability will depend on how much you know and the extent of guessing.

If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct how much credit will you lose for that part of the question?
question with options, you will lose of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing. With five choices, your chance of getting the question wrong is 80% when guessing, and every wrong answer costs you 1/4 of a point. In this case, leave it blank with no penalty. Guessing becomes a much better gamble if you can eliminate even one obviously incorrect response. If you can narrow the choices down to three possibilities by eliminating obvious wrong answers
