A student takes a multiple choice test consisting of 5 questions where there are 4 choices per question. Also, each question is worth 20 points. Suppose the student guesses on each question. Let X be the number of questions the student gets correct. The probability distribution for X is given below. Find the probability that the student gets at least a 60 on the test. Give your answer to four decimal places.

There are twenty-five multiple choice questions on an exam with four answer choices. If a student guesses the answer to every question, what is the probability that the student will get at least a D- on the test?

A student is taking a multiple-choice exam in which each question has five choices. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place five balls (marked Upper A comma Upper B comma Upper C comma Upper D comma and Upper E) into a box. She randomly selects one ball for each question and replaces the ball in the box. The marking on the...

A multiple choice test has 25 questions, each with 5 possible choices, exactly one of which is correct. The test is marked by giving four points to each correct choice, and subtracting one point for each incorrect choice. No points are either given or subtracted for questions for which no choice is selected. Mickey, Bianca, and Gerry each know the answer to 12 of the 25 questions, but are unsure about the rest. Mickey leaves the other 13 unanswered, whereas...

A test has 5 multiple choice questions with four choices with one correct answer each
QUESTION 11 A test has 5 multiple choice questions with four choices with one correct answer each. If we just randomly guess on each of the 5 questions, what is the probability that you get at least 1 questions correct? The probability a certain virus infects a random person is 0.2. If a random sample of 12 people is taken, what is the probability that exactly 5 people are infected?
