When U is true, P->U is always true. What are the possibilities for P? When P=0, P->U is true. When P=1, P->U is true.

So when it's P > U, whenever the right side of the conditional is true it's always true right. How about (P ^ U) with P-0 and U=?
It would be (0 ^ 1) or (1 ^ 1) right.
How about (P ^ U) with P-0 and U=? It would be (0 ^ 1) or (1 ^ 1) right.
The emphasized part is wrong because there is no 0 even though P is supposed to be 0.
