In a subset each element of the original may or may not appear - a choice of 2 for each element; thus for 3 elements there are 2 × 2 × 2 = 2³ = 8 possible subsets.

How many subsets of set A that contain exacly 3 elements set A has 10 elements?

You have three choices at a time without repeats. To do this multiply 10x9x8=720. This will give you duplicates, so divide the result by 1x2x3.


How many subsets does a set have if the set has four elements?

16 Recall that every set is a subset of itself, and the empty set is a subset of every set, so let {1, 2, 3, 4} be the original set. Its subsets are: {} {1} {2} {3} {4} {1, 2} {1, 3} {1, 4} {2, 3} {2, 4} {3, 4} {1, 2, 3} {1, 2, 4} {1, 3, 4} {2, 3, 4} {1, 2, 3, 4} * * * * * A simpler rationale: For any subset, each of the elements can either be in it or not. So, two choices per element. Therefore with 4 elements you have 2*2*2*2 or 24 choices and so 24 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.


What subset is?

For example, if we have a set of numbers called A which has 3 members(in our case numbers): A={2,5,6} this set has 8 subsets (2^3) which are as follow: the empty set: ∅ {2},{5},{6} {2,5},{2,6},{5,6} {2,5,6}

How many subset are there in 1 3 5 7?

A set of four elements has 24 subsets, since for every element there are two options: it may, or may not, be in a subset. This set of subsets includes the empty set and the original set, and everything in between.

How do you list 3 element subsets of a 7 element set?

If your 7 element set is {a, b, c, d, e, f, g}, you would list a 3 element subset by taking any 3 elements of the set eg., {a, d, g} or {b, c, f}, etc. To count all of the subsets, the formula is 7C3, where 7C3 is 7!/(3!*4!), or 35 different unique 3 element subsets of a 7 element set.


What is the number of elements in a set with 3 subsets?

No. of subsets = 2n - 1 3 = 2n - 1 3 + 1 = 2n - 1 + 1 4 = 2n 4/2 = 2n/2 2/1 = 1n/1 2 = n n = 2elements
