guesses are random each question has an equal chance of being correct or incorrect. After the quiz, they
try to predict their grades
Fatima thinks that the probability of getting all correct answers by guessing is equal to the probability of
getting exactly one correct answer by guessing. Alex disagrees. He thinks that the probability of getting
cactly one correct answer is greater
