Set Theory

Every field in the present world involves a set. The theory of sets was developed by German mathematician Georg Cantor while working on the “problems of trigonometric series”.

Question

Problem (5), 10 points
(a, 3 points) Consider the statement: 'If a, b, and c are odd numbers, then the sum a +
b + c will be odd.' Write the contrapositive of this statement.
(b, 2 points) True or False: If a set contains Ø as an element, it cannot be a partition of
another set
(c, 2 points) True or False: A statement and its converse are logically equivalent
(d, 3 points) We would like to prove by induction that n2-3n is even for every non-negative
integer n. Write the inductive hypothesis that you would assume in the inductive step of
the proof.
