Answer #1

The theoretical probability of moving 4 or less spaces in 1 spin = p = P(space = 1) + P(space = 2) + P(space = 3) + P(space = 4) = 0.125 + 0.125 + 0.125 + 0.125 = 0.5

the theoretical probability of moving 4 or less spaces in 3 spins if each spin is independent = p3 = 0.53 = 0.125

So,

Answer is:

0.125

    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...
