What are the odds of passing a test by guessing?
For every question, there are two outcomes: Either you answer correctly or you don’t. If you pick a random answer, the probability of guessing the right answer is one out of four, 1/4, or 0.25. Consequently, the probability of guessing wrong is a lot higher at 3/4 or 0.75.
What is the probability of getting 18 or more questions correct if you are randomly guessing?
