I want help with this Discrete Structure Math question.
Let T(x,y) = "x will take y", S(x) = "x is a CS student", H(y) = "y is a hard course" and P(y) = "y is an elective course" Assume the domain of x is all students and the domain of y is all courses. Select the negation of "Some CS students will not take all elective courses" O 1.All CS students will take some elective courses. O 2. All students will not take all elective courses. O 3. Some CS students will not take some elective courses. O 4. Some CS students will take all elective courses.
Rewrite each of these statements so that negations appear only within predicates (that is, so that no negation is outside a quantifier or an expression involving logical connectives.)
