What determines the number of subsets in a set?
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
Can we define the cardinal number as the number of subsets of that set?
No. The number of subsets of that set is strictly greater than the cardinality of that set, by Cantor's theorem. Moreover, it's consistent with ZFC that there are two sets which have different cardinality, yet have the same number of subsets.
What are the subsets for a fraction?
The subsets of a fraction refer to the individual components that make up the fraction. For example, the subsets of the fraction 3/4 would be the numerator (3) and the denominator (4). In set theory, a subset is a set that contains elements of another set, so in the context of fractions, the subsets are the parts that form the fraction.
Is empty set or null set is a subset of every set?
Yes,empty set or void set or null set is a subset of every set.In order to know the number of subsets of any set, first of all count the number of elements in the set and take the number of elements as the exponent of 2, then you will get the number of subsets of any set.
How many subsets does the set 1 2 3 have?
thenumber of subsets = 8formula: number of subsets =2n; wheren is thenumber of elements in the set= 2n= 23= 8The subsets of 1,2,3 are:{ }, {1}, {2}, {3}, {1,2}, {2,3}, {1,3}, {1,2,3}
