Question

a quick quiz consists of true/false questions followed by a multiple choice question with four possible answers (a,b,c,d). If both questions are answered with random guesses:

a.)are these two types of questions independent? yes or no

b.) find the probability that both responses are correct

Answer #1

a) Yes, these two types of questions are independent. Because guessing on second question is not dependent on guessing of first question.

b) P(both responses are correct) = P(first question is correct) * P(second question is correct)

= (1/2) * (1/4)

= 1/8 or 0.125

A quick quiz consists of a multiple-choice question with 6
possible answers followed by a multiple-choice question with 5
possible answers. If both questions are answered with random
guesses, find the probability that both responses are
correct.

A short statistics quiz consists of two multiple choice
questions. Each question had four possible answer choices (A, B, C,
and D).
a. Make a list of the possible answer keys for the quiz or make
a tree diagram for them.
b. How many possible answer keys are there?
c. If a student guesses at random for both questions, what is
the probability they get both questions right?
d. What is the probability that C was not the correct answer...

A quiz consists of 100 multiple choice questions. Each question

A quiz consists of 15 multiple-choice questions. Each question
has 5 choices, with exactly one correct choice. A student, totally
unprepared for the quiz, guesses on each of the 15 questions. a.
How many questions should the student expect to answer correctly?
b. What is the standard deviation of the number of questions
answered correctly? c. If at least 7 questions must be answered
correctly to pass the quiz, what is the chance the student
passes?
