The problem asks us to find the total number of festivals represented in the histogram. The histogram shows the number of countries represented at each festival. The x-axis represents the number of countries, and the y-axis represents the number of festivals. We need to add up the number of festivals for each category of countries.

1. Problem Description

The problem asks us to find the total number of festivals represented in the histogram. The histogram shows the number of countries represented at each festival. The x-axis represents the number of countries, and the y-axis represents the number of festivals. We need to add up the number of festivals for each category of countries.

2. Solution Steps

First, we need to read the number of festivals from the histogram for each range of countries:

- 0-5 countries: 1 festival

- 6-11 countries: 3 festivals

- 12-17 countries: 5 festivals

- 18-23 countries: 4 festivals

- 24-29 countries: 2 festivals

Now, we add these values together to find the total number of festivals:

$1 + 3 + 5 + 4 + 2 = 15$

3. Final Answer

15
