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 are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
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).
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.

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.

What is non-probability sampling?
Non probability sampling is where the samples are not selected randomly.

What is the probability that a randomly selected number from the set of 1-20 will be a multiple of 5?
Total number of possible selections = 20Number of possible successes = 4 (selection of 5, 10, 15, or 20)Probability of success = 4/20 = 20%

What is the probability that the number 23 will be randomly picked out of 100?
Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
