1. Show whether each of following arguments is valid or notusing propositional logic.The crop is good, but there is not enough water. If there is alot of rain or not a lot of sun, then there is enough water. Ifthere is not enough water, then there is not a lot of rain.Therefore, the crop is good and there is a lot of sun.

Determine whether each argument is valid. If the argument is valid, give a proof using the laws of logic. If the argument is invalid, give values for the predicates P and Q over the domain a, b that demonstrate the argument is invalid.∀x (P(x) ∨ Q(x))∴ ∀x Q(x) ∨ ∀x P(x)
