4. Given A = {1,2,3,4} Write the subset from one element , and two elements
Chake Answer
Subsets formed from one element is
Subsets formed from two elements are
{1}, {2}, {3}, {4}
{1,2}, {1,3}, {1,4}, {2,3}, {2,4} {3,4}

Venn Diagrams Venn Diagrams are visual representations regarding the Relationship between sets
The universal set U is shown by a rectangle , subset of the Universal set are drawn as ovals or circles inside the rectangleAnd arae usually labelled with a capital letter
AU

For example U= {all cars}A
U
A= {red cars}
The circular region A in the Venn diagram represents the set of red cars which are not red are represented by the green region
![Page 13: We will chake the answer](https://reader036.vdocuments.site/reader036/viewer/2022070416/5681513e550346895dbf5802/html5/thumbnails/13.jpg)
The following Venn diagrams show how two sets A and B(which are subsets of U) can be related
AU
B
Set B is a subset of set A , so B is drawn inside A
![Page 14: We will chake the answer](https://reader036.vdocuments.site/reader036/viewer/2022070416/5681513e550346895dbf5802/html5/thumbnails/14.jpg)
AUB
Some elements are common to both sets A and B
![Page 15: We will chake the answer](https://reader036.vdocuments.site/reader036/viewer/2022070416/5681513e550346895dbf5802/html5/thumbnails/15.jpg)
A UB
The two sets do not have common elements.
