<h3>Set theory</h3>
Set is defined as the arrangement of elements. They can be represented using the venn diagram.
Given the following sets
U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}
B={x: x^2>20} = {x >± 20}
From the set, can see that A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct
