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).

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).

If a student guesses on 10 questions on a multiple choice test abcd find the mean expected correct guess?
In a multiple-choice test with 4 options (a, b, c, d) for each question, the probability of guessing correctly for each question is ( \frac{1}{4} ). If a student guesses on 10 questions, the expected number of correct guesses can be calculated by multiplying the number of questions by the probability of a correct guess: ( 10 \times \frac{1}{4} = 2.5 ). Therefore, the mean expected correct guesses for the student is 2.5.
A student takes a 10 question multiple choice exam and guesses on each question Each question has five choices What is the probability of getting at least 6 correct out of the ten question?
To find the probability of getting at least 6 correct answers on a 10-question multiple-choice exam where each question has 5 choices (with only one correct answer), we can model this situation using the binomial probability formula. The probability of guessing correctly on each question is ( p = \frac{1}{5} ) and incorrectly is ( q = \frac{4}{5} ). We need to calculate the sum of probabilities for getting exactly 6, 7, 8, 9, and 10 correct answers. Using the binomial formula, the probability ( P(X = k) ) for each ( k ) can be computed, and then summed to find ( P(X \geq 6) ). The resulting probability is approximately 0.0163, or 1.63%.

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
