Question 444061: When taking a 19 question multiple choice test, where each question has 3 possible answers, it would be unusual to get (what x number?) or more questions correct by guessing alone.
Give your answer for (waht x number?) as a whole number.
You can put this solution on YOUR website! First, define "unusual." Is unusual defined as a probability of <.25, or <.1, or <.01, etc.? Surely, getting 18 or 19 correct via guessing is unusual.
