Find the union of two sets.Find the intersection of two sets.Test whether one set is a subset of another.Recognise the empty set and disjoint sets.📚 Quick Recap
A set is simply a well-defined collection of distinct objects. Sets form the basic language used to describe and organize almost every other area of mathematics.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1A = {a,b,c}, B = {b,c,d}. A ∪ B = ?
2A = {a,b,c}, B = {b,c,d}. A ∩ B = ?
3Is {1,3,5} ⊆ {1,2,3,4,5}?
4Is {1,6} ⊆ {1,2,3,4,5}?
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5The of two sets contains all their elements.
6The of two sets contains their common elements.
7Let A = {a,b,c}, B = {b,c,d}. Find A ∪ B.
8Let A = {a,b,c}, B = {b,c,d}. Find A ∩ B.
9Is {1,3,5} a subset of {1,2,3,4,5}?
🚀 Section C · Challenge ● CHALLENGE 5
10Is {1,6} a subset of {1,2,3,4,5}?
