Question

If u={1,3,5,6,9,11,13} then which of the following are proper subsets of u

Answer 1

To determine the proper subsets of a set, we need to understand the concept of proper subsets. The subsets that contain all the elements of the original set and have at least one additional element are the proper subsets.

Step-by-step explanation:

In order to determine which subsets of u={1,3,5,6,9,11,13} are proper subsets of u, we need to understand the concept of proper subsets.

A proper subset of a set is a subset that is not equal to the original set. It means that all the elements of the subset are also elements of the original set, but the subset has at least one element that is not in the original set.

Let's look at the options:

1. {1,3,5}
2. {1,3,6,9}
3. {1,3,5,11,13}
4. {3,5,6,9}

The proper subsets of u are options 1 and 4, because they only contain elements that are also in the original set u, but they have at least one element that is not in u.
