A set of cards contains cards numbered 1-8. Mrs. Jacob's class is conducting an experiment in which a card is drawn from
the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the
theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?

(1 point for showing all of your work) a. write and simplify an expression for the exact area of the sidewalk. (1 point for the answer) b. find the approximate area of the sidewalk. use 3.14 to approximate π. (1 point for the answer)
