The probability of a simple event can typically be calculated using the formula:
\[ P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]
Where:
- \( P(E) \) is the probability of the event,
- The "Number of favorable outcomes" refers to the outcomes that satisfy the event,
- The "Total number of possible outcomes" is the total number of outcomes that could possibly occur.
