Question: If set I = {1, 2, 3} and set J = {2, 3, 4}, what is the result of the operation I - J?

Options:

Correct Answer: {1}

Solution:

The operation I - J results in the elements of set I that are not in set J, which is {1}.

If set I = {1, 2, 3} and set J = {2, 3, 4}, what is the result of the operation I - J?

If set I = {1, 2, 3} and set J = {2, 3, 4}, what is the result of the operation I - J?

Step 1: Identify the elements in set I, which are {1, 2, 3}.
Step 2: Identify the elements in set J, which are {2, 3, 4}.
Step 3: Determine which elements in set I are not in set J.
Step 4: Compare each element in set I with the elements in set J.
Step 5: The element 1 is in set I but not in set J, so we keep it.
Step 6: The elements 2 and 3 are in both sets, so we do not keep them.
Step 7: The result of the operation I - J is the set containing only the element 1, which is {1}.

Set Difference – The operation I - J represents the set of elements that are in set I but not in set J.
