Create A Set Representing A Real Life Group Of Th

Create a set representing a real-life group of "things" and write it in roster notation. The members of the set can be groups such as tools you will use in your future profession, breeds of dogs, or your siblings or children. It is even okay to use letters, numbers, and/or symbols. The choice is yours, and humor and creativity are encouraged.

Use roster notation to create and write two proper subsets of your original set.

Find the union of the sets.

Find the intersection of the sets.

Find the complement of each of the sets.

Note: All sets should be written in roster notation.

Paper For Above instruction

In this paper, I will create a set representing a real-life group of “things” related to my personal interests and future profession, specifically, a set of essential tools I might use as an aspiring artist. I will then develop two proper subsets from this original set and perform basic set operations including union, intersection, and complements. These operations will help illustrate fundamental concepts in set theory, which are vital in understanding collection-based mathematics and logic.

My original set, representing tools I use or might use in my artistic pursuits, is as follows:

S = {pencils, paintbrushes, palette knives, charcoal, sketchpad, eraser, blending stumps, measuring ruler, colored pencils}

This set encompasses various physical tools critical for drawing and painting, and the inclusion of different types of pencils and brushes reflects the diversity of mediums an artist employs.

Next, I will define two proper subsets of this original set:

A = {pencils, sketchpad, eraser, colored pencils}

B = {paintbrushes, palette knives, blending stumps, measuring ruler}

Both subsets are proper; that is, neither is equal to the original set, and each contains some but not all elements of S.

Now, I will perform the set operations, beginning with the union of A and B:

A ∪ B = {pencils, sketchpad, eraser, colored pencils, paintbrushes, palette knives, blending stumps, measuring ruler}

This union combines all distinct elements from both subsets, illustrating the complete collection of tools covered when considering both artistic and measuring tools.

Next, the intersection of A and B:

A ∩ B = ∅

Since sets A and B are disjoint with no shared elements, their intersection is the empty set, highlighting that these subsets focus on different categories of tools without overlap.

The complements of A and B within the universal set S are as follows:

A' = {paintbrushes, palette knives, charcoal, measuring ruler, blending stumps}

B' = {pencils, sketchpad, eraser, colored pencils}

The complements show the elements in the universal set that are not part of either subset, thus representing the tools outside each specific category, which for A are mainly painting and measuring tools, and for B are drawing tools.

In conclusion, this exercise demonstrates the practical application of set theory to real-world objects, such as artistic tools. Understanding how to form sets, subsets, their union, intersection, and complements allows for better organization, analysis, and categorization of items. These skills extend beyond mathematics into everyday problem-solving, project management, and logical reasoning.
