Question

If the two spinners below are spun, what is the probability that the numbers will match? 1/4 1/6 1/12 1/3​

Answer 1

1/4

Explanation:

• Probability of getting a number on Spinner 1 = 1/3
• Probability of getting a number on Spinner 2 = 1/4
• Sample Space = 12 entries

Sample Space

• {(1,1)(1,2)(1,3)(1,4)(2,1)(2,2)(2,3)(2,4)(3,1)(3,2)(3,3)(3,4)}
• Probability of getting the same number = 3/12 = 1/4
