Logician #2: “I want to see Crazy Rich Asians and Venom.”

Logician #3: “I want to see Crazy Rich Asians, Searching, and Venom.”

Let L be the set of the three logicians and M be the set of the four movies. The predicate P(x,y) means “Logician x wants to see movie y. The predicate x y means that x and y are not the same logician.
Translate the following statements into English, then determine whether they are true or false. If they are false, give the negation symbolically, as well as in English.
a. ∀x ∈ L ∃y ∈ M,P(x,y)

b. ∃x ∈ L ∀y ∈ M,P(x,y)

c. ∀y ∈ M ∃x ∈ L,P(x,y)

d. ∃y ∈ M ∀x ∈ L,P(x,y)

e. ∀x ∈ L ∀y ∈ L ∃z ∈ M,[P(x,z)∧P(y,z)]

f. ∀x ∈ L ∃y ∈ L ∃z ∈ M,[x 6= y∧P(x,z)∧P(y,z)]
