b. Calculate the theoretical probability of moving 10 or more spaces in 3 spins (i.e. obtaining the sum of the spins to be 10 or greater). Use your probability distribution in part (a) and note that spins are independent. (Hint: Recognize that getting a 1 on spin 1, a 2 on spin 2, and a 1 on spin 3 is a different result than getting a 1 on spin 1, a 1 on spin 2, and a 2 on spin 3.) Show how you obtained this probability and provide the answer.

Problem 1: Game Spinner We will be comparing empirical (relative frequencies based on an observation of a real-life process) to theoretical (long-run relative frequency) probabilities. We will use StatCrunch to simulate this process using a board game spinner three times so that we can determine the total number of spaces moved in three turns. The board game spinner looks like the image below. The spinner is equally likely to land on any given section. f) Calculate the theoretical probability of...

O A. Yes, because the distribution is symmetric. OB. No, because some of the probabilities have values greater than 1 or less than 0. OC. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. O D. No, because the total probability is not equal...
