P: X–most–BP: ?C: X–most–C

Some/most

Why is it that sometimes the contrapositive is the same most/some but sometimes it's not (like it is here)? I'm confused.

Hi @kuriku, thanks for your post.

The rule is that "most" statements reverse as "some" statements.

Thus, the statement X-most-C will reverse as C-some-X.

"Some" statements reverse as "some" statements.

Thus, the statement A-some-B will reverse as B-some-A.

Hope this helps! Please let us know if you have any additional questions.
