Question

A = {1, 2, 3, 4, 5} what is the answer PLZZ show how to solve this sum​

Answer 1

You Question seems to be wrong

Don't worry This will help you out

Subset

A = { 1, 2 , 3, 4, 5, 6, 7, 8 }

B = { 2, 4 ,6 ,8 }

This shows,

Every element of set B is also an element of set A

therefore B C A.

This can be represented by the Venn diagram as shown in the attachment

More

if A and B are two given sets and every element of Set B is also an element of said a then B is a subset of A.It can be read as 'B is a subset of A ' or ' B subset A '

Example ⬇️

If A = { 1, 3, 4, 7, 8 } then write all possible subsets of A.

i.e P = { 1, 3 } , T = { 4, 7, 8 } , V = { 1, 4, 8 } , S = { 1, 4, 7, 8 }

In this way many subsets can be written.
