I was working on a logical problem. In this problem I have a problem with the statement made by B.

B said I wasn't I know C did it

I thought that the second statement of B means C did it.

In the accepted answer you can see that C has (f,t) which means his first statement is false and the second is true.

If second statement of B is false then how can C be guilty?

I think there is no difference between saying I know C did it and C did it.

If there is a difference between the statements then please tell me?


The opposite of "C did it" is "C didn't do it."

By contrast, the opposite of B's seconds statement, "I know C did it" is "I don't know whether/if/that C did it."

It is possible that C did it but B did not know about it; therefore, C can be guilty while B's second statement is false.
