A multiple choice quiz has4 questions. Each question has 5 possible answers, only one of which is correct. A student has not studied for the quiz and guesses randomly on each question. What is the probability that the student gets at least one correct answer? Show your calculation, and write your answer as either a reduced fraction or a decimal rounded to four places.
Homework Answers
We have here, n = 4 and p = 1/5 = 0.2
