20 maj 2022 · Exercise \(\PageIndex{1}\): Set Operations. Let \(A = \{1, 5, 31, 56, 101\}\), \(B = \{22, 56, 5, 103, 87\}\), \(C = 41, 13, 7, 101, 48\}\), and \(D = \{1, 3, 5, 7...\}\) Give the sets resulting from: \(A \cap B\) \(C \cup A\) \(C \cap D\) \((A \cup B) \cup (C \cup D)\) Answer. 1. \(A \cap B =\{ 5, 56 \}\) 2. \(C \cup A=\{1, 5, 7, 13, 31, 41 ...
To prove a set is a subset of another set, follow these steps. (1) Let \(x\) be an arbitrary element of set \(S\). (2) Show \(x\) is an element of set \(T\). This proves every element of set \(S\) is an element of \(T\). Example: Prove \(\mathbb{Z} \subseteq \mathbb{Q}.\) Let \(x \in \mathbb{Z}.\) \(x=\frac{x}{1}.\) See if you can continue this ...

In worksheet on set we will solve 12 different types of questions. The questions on sets are basically related on elements of set and notation of a set, representation of a set, cardinal number.
Set of prime numbers: {2, 3, 5, 7, 11, 13, 17, ...} And so on. We can come up with all different types of sets. We can also define a set by its properties, such as {x|x>0} which means "the set of all x's, such that x is greater than 0", see Set-Builder Notation to learn more.
