A jar contains 3 balls: one blue, one red, and one yellow. We repeat drawing balls from the jar with replacement until all three balls are drawn at least once. 1. What is the chance that the blue ball is drawn before the red balls? Answer: 2. What is the chance that the last ball is yellow? Answer: 3. Let /V denote the total number of times we draw a ball from the jar in this experiment. What is the expected value of N? (Hint: Write N as a sum 1 + Nj + No where N and No are appropriate geometric random variables.) EN = [If necessary, round your answers to three decimal places.]
