Answer

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).
