If it swims or has gills, it is fish

Question

I want the symbolic form of this.

Answer 1

A = proposition "it swims"

B = proposition "it has gills"

C = proposition "it is fish"

∨ means "or"

⇒ means "implies"

 

In symbolic form,

 

A ∨ B ⇒ C

 

That is the symbolic form, regardless of the truth of the propositions.

Answer 2

My brother swims but he is not a fish.
