Two sets A and B can be joined together with A U B. This would be all the elements in both sets. If A = {a,b,c} and B = {x,y,z} then A U B = {a,b,c,x,y,z}.
Two sets A and B can intersect (the symbol is an upside down U). In the above example, the intersection of A and B is the empty set, because they have no common members. As an example where they do have some common members, let A = {a,b,c,d,e,f} and B = {e,f,g,h}. Then A intersect B = {e,f} because those are the members common to both.
Also, a set can be contained within another set. The containment symbol looks like a C with a line drawn under it. Let A = {a,b,c,d,e,f} and let B = {b,d,f}. Then B is contained within A, i.e., B C A. (Sorry. You'll have to imagine the line under the C.)
Inverse proportion
yes
It is a mapping which assigns one or more outputs to each set of one or more inputs. A relationship need not be a function.
It suggests that there is very little evidence of a linear relationship between the variables.
Relationship can also be represented by a set of ordered pairs called a function.

There may not be any relationship between number of sets and number of elements. You can have just one set or thousands of sets. Similarly, you can also have just one element (rare) or thousands of elements.
There are various types of sets based on the relationship between their elements. Some common types include: Empty set: A set containing no elements. Singleton set: A set with only one element. Finite set: A set with a countable number of elements. Infinite set: A set with an uncountable number of elements. Subset: A set where all elements are also elements of another set. Proper subset: A subset that is not equal to the original set. Universal set: A set that contains all elements under consideration. Disjoint set: Sets that have no common elements. Power set: A set consisting of all possible subsets of a given set.
