For the statement

write the statement symbolically using parentheses and determine whether it is a negation, conjunction, disjunction, conditional or biconditional

So in statement part it would be biconditional?


John G.

Overall it's actually a disjunction, but it does also contain a biconditional in the first part.  You need to look the the parentheses as one piece and the ~r as the second piece.  Since the symbol between the two pieces is an "or", it's a disjunction.

Oh okay I wasn't looking at it as one piece . I was looking at everything separate . Even in my notes everything is broken down into pieces
