Q
Q: Which of the following is a subset of {1, 2, 3}?
Solution:
A subset is a set that contains elements from another set. {1, 2} is a subset of {1, 2, 3}.
Steps: 5
Show Steps
Step 1: Understand what a subset is. A subset is a set that includes some or all elements from another set.
Step 2: Look at the original set, which is {1, 2, 3}.
Step 3: Identify the possible subsets. For example, {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, and the empty set {} are all subsets of {1, 2, 3}.
Step 4: Check if {1, 2} is included in the list of subsets. Since {1, 2} contains elements from {1, 2, 3}, it is a valid subset.
Step 5: Conclude that {1, 2} is indeed a subset of {1, 2, 3}.
