Q: If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}, what is A ⊆ B?
Solution:
Set A is a subset of set B because all elements of A are contained in B. Therefore, A ⊆ B is True.
Steps: 6
Show Steps
Step 1: Identify the elements in set A, which are {1, 2, 3}.
Step 2: Identify the elements in set B, which are {1, 2, 3, 4, 5}.
Step 3: Check if every element in set A is also in set B.
Step 4: Look at each element in A: 1 is in B, 2 is in B, and 3 is in B.
Step 5: Since all elements of A (1, 2, and 3) are found in B, we conclude that A is a subset of B.
Step 6: Therefore, we can say A ⊆ B is True.
