Explanation:

Step1: Identify frequencies for each post count

For 0 posts: frequency = 1; 1 post: 2; 2 posts: 2; 3 posts: 5; 4 posts: 2; 5 posts: 0; 6 posts: 4; 7 posts: 3; 8 posts: 2.

Step2: Sum all frequencies

Calculate \(1 + 2 + 2 + 5 + 2 + 0 + 4 + 3 + 2\).
First, \(1+2=3\); \(3+2=5\); \(5+5=10\); \(10+2=12\); \(12+0=12\); \(12+4=16\); \(16+3=19\); \(19+2=21\).
