Rayna writes each letter of her name—R, A, Y, N and A—on a separate piece of 1-by-1 paper. She then puts the 5 pieces of paper in a bag and randomly selects one of the 5 pieces. What is the probability that she selects the piece with the R written on it? Express your answer as a common fraction.
Well, since Rayna is a name with 5 letters, and the question is asking for the probability for R, and that's only 1 letter.
So the answer must be 1/5.
