Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If set A = {1, 2, 3} and set B = {3, 4, 5}, create an equivalence relation that relates elements of A to elements of B.

💡 Hint: Consider how you might categorize elements across the two sets.

Challenge 2 Hard

Given a set S = {x, y, z, w} and the partition {{x, y}, {z, w}}, formulate the equivalence relation and justify its reflexivity, symmetry, and transitivity.

💡 Hint: Revisit how to articulate properties based on pairs.
