Question

On
a multiple-choice test with nine questions, each question has for
possible answers, one of which is correct. For students who gets it
all answers, find the variance for the number of correct
answers.

Answer #1

A
quiz consists of 12 multiple-choice questions. Each question has 5

A test consists of 30 multiple choice questions, each with five

Find the mean and the standard deviation of the number of
correct answers.

. A quiz has 25 multiple choice questions. Each
question has 3 possible answers, one of which is correct. A correct
answer is worth 4 points (a ticket with the value of 4), but a
point is taken off for each incorrect answer (a ticket with the
value of -1). A student answers all 25 questions by guessing at
random.
a) Present the problem with an appropriate box model.
Find the expected value and the standard error for the sum...

For each question on a multiple-choice test, there are five
possible answers, of which exactly one is correct. If a student
selects answers at random, give the probability that the first
question answered correctly is question 4.

When taking a 10 question multiple choice test, where each
question has 4 possible answers, it would be unusual to get or more
questions correct by guessing alone.

Find the indicated binomial probability.
A multiple choice test has 10 questions each of which
has 4 possible answers, only one of which is correct. If Judy, who
forgot to study for the test, guesses on all questions, what is the
probability that she will answer exactly 3 questions correctly?

On a Multiple Choice test, each question has six possible
answers. If you make a random guess on all 10 questions, what is
the probability that you are going to get 8 out of 10 correct?

A test consists of 10 multiple choice questions, each with five
possible answers, one of which is correct. To pass the test a
student must get 60% or better on the test. If a student randomly
guesses, what is the probability that the student will pass the
test? Please show work
