How many elements are in a sub1 intersect a sub 2 which equals a null set
when a sub 1 =12 and a sub2 = 18
when a sub 1 =12 and a sub2 = 18
The Null Set, also known as the empty set, is a set that contains no elements. It is denoted by the symbol ∅ or { }.
"sub1 intersect sub2" refers to the intersection of two sets, which is the set of all elements that are common to both sub1 and sub2.
Yes, the Null Set is a subset of all sets, including itself. This is because the Null Set contains no elements, and all sets must contain the elements listed in their definition.
No, the Null Set cannot be a proper subset. A proper subset is a subset that is not equal to the original set. Since the Null Set does not contain any elements, it is always equal to itself and cannot be a proper subset.
The cardinality, or size, of the Null Set is 0. This is because the Null Set does not contain any elements, and the cardinality of a set is defined as the number of elements in the set.
