Question

Given {1, 3, 5, 7} - {1,3}. Find the difference.

A. {1,3}
C. {1, 3, 5}
B. {5,7}
D. {1,5,7}

Answer 1

The difference between the sets {1, 3, 5, 7} and {1,3} is {5, 7}, which is the remaining elements after removing the shared elements from the first set.

Step-by-step explanation:

The question asks to find the difference between two sets: {1, 3, 5, 7} and {1, 3}. The difference of two sets is found by removing all the elements of the second set from the first set. In this case, removing 1 and 3 from the first set leaves us we need to remove the elements in the second set from the first set. The result is the set {5, 7}. Therefore, the correct answer is B. {5, 7}.
