Read & Answer Carefully.

Suppose that five students are in a seminar class. The instructor writes their names on ping-pong balls and draws a name out of a hat to determine which student will lead class that day. Each week, the instructor starts with the same set of five ping-pong balls.

Let's call the students Sam, Mary, Renee, Noah, and Tiffany. Define the probability distribution in the form of a table.

Suppose that Noah was selected to lead during week one. What is the chance that he will be selected to lead during both weeks one and two?
