The formula to calculate the Volleyball Passing Percentage (PP) is:
\[ PP = \frac{PG + PP}{TA} \times 100 \]
Where:
Let's say the number of good passes is 30, the number of playable passes is 20, and the number of passing errors is 10. Using the formula:
\[ PP = \frac{30 + 20}{30 + 20 + 10} \times 100 \]
We get:
\[ PP = \frac{50}{60} \times 100 \approx 83.33 \% \]
So, the passing percentage is approximately 83.33%.
