Calculating the Total Number of Participants in the Voting

To calculate the total number of participants in the voting, we can use the following approach:

1. Let's denote the number of people who voted for football as F and the number of people who voted for volleyball as V. 2. We are given that 13 people voted for football and 21 people voted for volleyball. 3. Additionally, we know that 10 people voted for both football and volleyball.

Using this information, we can calculate the total number of participants in the voting.

Calculation

Let's denote the total number of participants as T.

We can use the principle of inclusion-exclusion to find T:

T = F + V - (Number who voted for both football and volleyball)

Substituting the given values:

T = 13 + 21 - 10

T = 24

Therefore, the total number of people who participated in the voting is 24.
