Each family of elements has its own set of characteristics that each of the elements possess.
Add each number in the set and divide by the amount of elements in the set.
It is 2^100 because each of 100 elements can either be in or out. By the way the answer is 2^100-101, because there is one subset with no elements at all (the empty set)!
(5 x 4 x 3)/(3 x 2) = 10
This is a method describing a set by listing each element of the set inside the symbol {}. In listing the elements of the set, each distinct element is listed once and the order of the elements does not matter.
Since 213 = 8192, there are 8192 elements in the set.
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.
A set with 9 elements has 2^9 = 512 subsets.
The number of subjects will depend on what the elements of the set are. The number of subsets is 2a.
Two sets are said to be equivalent if the elements of each set can be put into a one-to-one relationship with the elements of the other set.
The possible relationships between two sets (here arbitrarily named A and B) are:If each element of set A is also element of set B (and vice versa), the two sets are equal.If no element of set A is element of set B (and vice versa), the two sets are disjoint.If all elements of set A are also elements of set B, the set A is a subset of set B. If set B contains elements not found in set A, the set A is a proper or strict subset of set B. Set B is called supersetresp. proper superset of A.If set A and set B share some elements, but each set also has elements not found in the other set, the two sets intersect.
