Spinner, Math, Probability

Once upon a time, before the era of fidget spinners dominated classrooms, a spinner was a staple tool for modeling random processes, allowing students to grasp the concept of uncertainty, data trends, and mathematical structures. This mathematical spinner can also serve as a modern-day "fidgeter." The standard board has a diameter of 80mm, featuring both numbers (1, 2, 3, 4, 5, 6) and letters (A, B, C, D, E, F). The pointer is intentionally designed to be slightly loose for effortless spinning and removal. Students can engage with the following questions to deepen their understanding: (1) What's the likelihood of landing on an even number? (2) What's the probability of getting a prime number? (3) If you spin twice, what's the likelihood of getting a sum of 8? (4) If you spin five times, what's the probability of getting all prime numbers? (5) What's the probability of landing on a vowel?
