Find the mean and standard deviation of the binomial probability distribution defined by x being the number of correct answers on a 10 question multiple choice quiz, if each question has four possible answers, and each answer is a guess.

Step 1
The number of correct answers on a 10 question quiz can range from 0 to 10. The mean of a binomial distribution is given by the formula: mean = n * p where n is the number of trials (in this case, 10 questions) and p is the probability of success (in this Show more…
