How many patterns of subset can you make from a set?

given any set of n objects, there are 2^n subsets. This comes from the fact that each item is either in or not in any given subset. So for all n objects, each one has two possibilities, either it is or is not in a subset. Then 2^n come from the multiplication principle.


Can two points determine a plane?

No, 2 points define a line, 3 points define a plane.


How do you write out a subset?

To write out a subset, list all the elements of the subset within curly braces. For example, if you have a set ( A = {1, 2, 3, 4} ) and you want to write out the subset containing the first two elements, you would denote it as ( B = {1, 2} ). Ensure that the elements are distinct and that the subset reflects the original set's elements. You can also indicate that it is a subset by using the subset symbol ( \subseteq ) (e.g., ( B \subseteq A )).


What are example of proper subset?

{1,2,4.7} is a proper subset of {1, 2, 3, 4, 4.7, 5}


Why does a set containing n element have 2n subsets?

I presume you meant 2^n (2 raised to the nth power), not 2*n (2 times n). That's answers.com's character set problem again (I trust, giving you the benefit of the doubt). The answer is that for each of the n elements, it is either in any particular subset or it isn't. Which elements are in and which are not in a subset defines the subset. So for example, if n is 3, say a, b, and c, there are 2 sub-collections of the set of all subsets: those containing a and those not containing a. In each of those sub-collections, there are 2 sub-collections based on whether they contain b, for a total of 4 (2*2) sub-collections. Finally, of each of these 4, there are 2 subsets: those containing c and those not containing c, for a total of 8 (2*2*2 or 2^3) subsets. Got it?

Yes it does, because of its 2 ends


What is subsets and proper subsets?

A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.

What is a subset and a proper subset?

A set is a subset of a another set if all its members are contained within the second set. A set that contains all the member of another set is still a subset of that second set.A set is a proper subset of another subset if all its members are contained within the second set and there exists at least one other member of the second set that is not in the subset.Example:For the set {1, 2, 3, 4, 5}:the set {1, 2, 3, 4, 5} is a subset set of {1, 2, 3, 4, 5}the set {1, 2, 3} is a subset of {1, 2, 3, 4, 5}, but further it is a proper subset of {1, 2, 3, 4, 5}


What is an subset?

An improper subset is identical to the set of which it is a subset. For example: Set A: {1, 2, 3, 4, 5} Set B: {1, 2, 3, 4, 5} Set B is an improper subset of Set Aand vice versa.
