Problem
You have a six-sided fair number cube that is numbered 1-6. What is the theoretical probability that you will roll a 4? \( \frac{1}{6} \) \( \frac{1}{36} \) \( \frac{1}{30} \) \( \frac{2}{3} \)
Solution
Step 1 ：\( P(\text{rolling a 4}) = \frac{\text{number of successful outcomes}}{\text{total number of outcomes}} \)
Step 2 ：\( P(\text{rolling a 4}) = \frac{1}{6} \)
