Question

In a six-question multiple-choice test, there are four possible answers for each question. For a person who guesses at each question, what is the expected number of correct answers?

Answer 1

1 answer. (possibly 2)

Explanation:

There's
`(1)/(4)` chance they get the correct answer for a question.

That means if they answer 4 questions, they can expect 1 answer to be correct. If they answer 6 questions, they can expect 1.5 answers to be correct but you can't have 0.5 of an answer so they can expect 1 question answered correctly.

Answer 2
