Question

Suppose you are taking a multiple choice exam with 61 questions, each with 4 possible answers. If you were to guess at random for each question, how many questions would you expect to get right

Answer 1

15.25

Explanation:

The probability of getting a question right is 1/4 because there are 4 possible answers, and you're just guessing randomly.

You can expect to get 1/4 of the questions right.

`(1)/(4)* 61 =15.25`
