X' is the set of blood types that type AB- cannot donate blood to

Y is the set of blood types that type AB+ can donate blood to

From the table, AB- cannot donate blood to:

(This is all the blood types minus the ones that can receive from AB-)

U - {AB+, AB-} = {A+, B+, A-, B-, O+, O-} = X'

Y = {AB+}

So the negations:

X = {AB+, AB-}

Y' = {A+, B+, AB-, A-, B-, O+, O-}

And this is our final answer
