Question

You have a 5-question, true-false quiz. What is the probability that you choose each answer at random and get 4 of the questions correct?

Answer 1

1/16

Explanation:

you have a 1/2 chance to get the answer right. Each time you add a new answer, you multiply the current chance by the chance of getting the new answer correct. So, the chance of getting 4 answers correct is 1/2^4, or 1/16
