Solution:-

a) Assuming P(x) denotes 'x is person' then the statement All students are persons can be represented as where domain constitutes All students.


b) Assuming S(x) denotes ' x is a student' , C(x) denotes ' x has taken CS major' then the statement Some students are CS majors can be represented as where domain constitutes students in the class.


c) Assuming C(x) denotes ' x has taken CS major ' , V(x) denotes ' x likes video games' then the statement Not all CS majors like video games can be represented as where domain constitutes students in the class.
