Explain why the empty set is a subset of every set.
choose the correct answer below.
a. if all elements in set a are also elements of set b and all elements in set b are also elem
in set a, then a and b are subsets. if a is the empty set, then there can never be any
elements in a, much less elements in a that belong to b.
b. if there is at least one element of set a that is not an element of set b, then a is not a sub
of b. if a is the empty set, which contains no elements, then there can never be any
elements in a, much less elements in a that do not belong to b.
c. if there is at least one element of set a which is also
e is at least one element of set a which is also an element of set b, then a is a subset
of b. if a is the empty set, which contains no elements, then there can never be any
elements in a, much less elements in a that belong to b.
