Tina puts the letters of the word RADAR on pieces of paper and puts them in a bag. She draws two letters without
looking at them. The first piece of paper is not replaced before the second piece is drawn. What is the probability that
Tina draws an R twice? (HINT: First find P(R). Then find P(R) assuming that she already picked one “R”. Then multiply.)
