All questions are worth 5 points for a total of 100 points possible on the exam. A student randomly guesses on all questions.

1 What is the probability that a student gets a 0 on the exam?

2 What is the probability that a student gets 3 true or false questions and 7 multiple choice questions correct?

3 What is the probability that the student gets a 95 or higher on the exam?
