It depends on the set x. If set x is of cardinality n (it has n elements) then it has 2n subsets.

How many subsets in an empty set?

The empty set has only one subset: itself. It has no proper subsets.


How many proper subsets does a set with four elements have?

A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.


How many subsets are in the set 12345?

Number of subsets with no members = 1Number of subsets with one member = 5.Number of subsets with 2 members = (5 x 4)/2 = 10.Number of subsets with 3 members = (5 x 4 x 3 /(3 x 2) = 10.Number of subsets with 4 members = (5 x 4 x 3 x 2)/(4 x 3 x 2) = 5.Number of subsets with 5 members = 1Total subsets = 1 + 5 + 10 + 10 + 5 + 1= 32.A set with n elements has 2n subsets. In this case n = 5 and 25 = 32.The proof in the case that n = 5 uses a basic counting technique which say that if you have five things to do, multiply together the number of ways to do each step to get the total number of ways all 5 steps can be completed.In this case you want to make a subset of {1,2,3,4,5} and the five steps consist of deciding for each of the 5 numbers whether or not to put it in the subset. At each step you have two choices: put it in or leave it out.


How do you get the number of the subsets in a set?

A finite set with N distinct elements has 2N subsets.


How many subset can you form in algebra?

If you have a set with "n" elements, you can form 2 to the power n subsets. This is because each element of the original set has two options: to be included, or not to be included, in a subset. So, for instance, for a set with four elements, you have 2 x 2 x 2 x 2 different possibilities to create subsets (2 to the power 4).Note 1: This includes the empty set, and the original set itself. Note 2: The set of all subsets is known as the power set. Note 3: It has been proven that the power set (of size 2 to the power n) is ALWAYS larger than the original set (of size n) - even for infinite sets. That means that the power set of an infinite set gives you a larger kind of infinity.
