Question

fill in the blank so that the resulting statement is true. set a is a subset of set b, expressed as ____, __ means that ____ choose the correct answer below. a. set a is a subset of set b, expressed as ( asubseteq b ), means that every element in set a is also an element in set b. b. set a is a subset of set b, expressed as ( asubseteq b ), means that every element in set a is also an element in set b and sets a and b are not equal (( a
eq b )) c. set a is a subset of set b, expressed as ( asubseteq b ), means that every element in set a is also an element in set b and sets a and b are not equal (( a
eq b )) d. set a is a subset of set b, expressed as ( asubseteq b ), means that every element in set a is also an element in set b and sets a and b are not equal (( a
eq b ))

Explanation:

The definition of a subset \(A \subseteq B\) states that every element present in set \(A\) must also be an element of set \(B\); it does not require \(A\) and \(B\) to be unequal (that is the definition of a proper subset, denoted \(A \subset B\)).

Answer:

B. Set A is a subset of set B, expressed as A⊆B, means that every element in set A is also an element in set B.
