How does the probability improve of choosing the one correct answer as incorrect answers are eliminated one at a time from 5 multiple choice question such as those found on the SAT?
Probability of hitting the bull's-eye on the next random shot after eliminating . . . - no answer . . . . . 20% - 1 answer . . . . . . 25% - 2 answers . . . . . 331/3% - 3 answers . . . . . 50% - 4 answers . . . . . 100% - 5 answers . . . . . zero Probability of choosing the one correct answer increases significantly from these figures if you actually know something about the subject.
What is the probability of answering 50 questions right out of 100?
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.
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 zero for feelings on the Myers-Briggs test?
In order to calculate such probability, you have to know the number of questions in that particular Myers Briggs test that refer to the Thinking/Feeling dichotomy. Assuming that you will pick answers randomly, the probability will be lower when there are more questions. For 8 questions on T/F preference, there is a 12.5% probability for a score of 0 on Feeling. For 16 questions, the probability is 6.2%. For 32 questions, the probability is 3.1%. etc. If you pick your answers according to your own beliefs, it would be very difficult to assess such a probability. However there will be a approx. 30% higher chance for a man to score 0 on Feeling than for a woman.

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.

86.25% To verify: Divide number of incorrect questions (11) by number of original questions (80); answer expressed as a percentage is 13.75%. That's the number of incorrect answers, therefore 100% - 13.75% = 86.25% is the number of correct answers.
