In history class, colin takes a multiple-choice quiz. there are 10 questions. each question has five possible answers. to the nearest percentage, what is the probability that colin will get exactly 3 questions correct if he guesses an answer to each question?

Step-by-step explanation:

If the discrete random variable X represents the number of correct Colin responses then X can be represented by a binomial distribution with parameters p, n, x.

In this case p represents the probability that colin gets a correct answer, n represents the number of questions.

Where:

the correct answer is x/3+10≥32
