Answer:
See explanation and picture attached
Step-by-step explanation:
A set can be described by<em> listing all of its elements</em>.
For example, A = { 2, 4, 6, 8}, which we read as
“A is the set whose elements are 2, 4, 6 and 8”.
The four elements of the set are separated by commas, and the list is enclosed between curly brackets.
A <em>set can also be described by writing a description of its elements</em> between curly brackets.
Thus the set A above can also be written as
A = { even natural numbers less than 9 }, which we read as
“A is the set of even natural numbers less than 9”.
A set can also be described graphically by using Venn diagrams, which are simply circle shaped drawings showing the elements inside.
In our case U={1,2,3,4,5,6,7,8,9,10,11,12} A={1,2,3,4,6,12} B={1,2,4,8}
