If You guesses on a multiple choice question and there were 4 choices for the problem what is the percent of probability you will guess wrong?
Hannabanana080
If there are 4 choices and you randomly choose one, you have a 25% chance that it will be correct, with 75% that it will be wrong. However, if there is one answer that you know is not correct, you can eliminate that one. Then if you choose from the remaining three, you will have increased your chances of getting it right to 33%. That doesn't sound like a whole lot, but it really would help you.

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.
A student takes a 5 question quiz with 4 choices for each question if the student guesses at random on each question what is the probability that the student gets exactly 4 questions correct?
This is abinomial distribution; number of trials (n) is 5, probability of success (p) is 1/4 or 0.25. With this information you can go to a Binomial Distribution Table and find the solution. Within the section of values for n=5 and p=.25, read from the section the probability of 4 which is 0.0146 (see related link for table).

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

A student takes a 20-question multiple choice exam with five choices for each question and guesses on each question Find the probability of guessing at least 15 out of 20 correctly?
15%? (My math sucks - I probably got that wrong).

Preet writes a multiple-choice test.The test has 5 questions.Each question has 4 possible answers.Preet guesses each answer.Find the probability of each event?
Each guess has a 25% chance of being correct and a 75% chance of being wrong. Guessing right or wrong on one question does not affect the odds on the next one.
How is the term probability related to genetics?
The term probability is related to genetics because they both give guesses about how something that might be the outcome of something
A multiple choice quiz consists of 6 questions each with 4 possible answers If a student guesses at the answer to each question then the mean number of correct answers is?
If there are four possible answers to a question, then a guessed answer would have a probability of 1 in 4. If there are six questions, then the mean number of correct answers would be six times 1 in 4, or 1.5
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.
