Answer:
The statement is false.
Explanation:
The symbol ⊆ is used in set theory to represent the subset relationship.
The notation A ⊆ B signifies that set A is a subset of set B, indicating that every element of set A is also present in set B.
The given statement {4, 5, 6, 7} ⊆ {4, 5} states that the numbers in the first set are also present in the second set.
The statement is false, as the first set {4, 5, 6, 7} contains the numbers 6 and 7 that are not present in the second set {4, 5}. Therefore, {4, 5, 6, 7} is not a subset of {4, 5}, and the statement is false.
