MATH 2. Five shoppers buy Charmin toilet paper. One Charmin out of 10 in this batch is defective-unsqueezable. You

want to save everyone from this catastrophe, so you stop them at the door and ask to squeeze their Charmin.

After squeezing 5 rolls, what is the probability that you have located 1 or more defective Charmins?

3. Pick a number: 1, 2, 3, or 4. Write it down. If each student in a class of 48 were also to pick a number, how

many would you guess had selected the same number that you did?
