Answer 1

Answer:

AUB = (1,3,9,11,13),Yes B is a subset of set A.

Step-by-step explanation:

1.If the number of elements in second set is similar to the first then it is a subset.eg.the question number 2 in your question.2.If the elements in a set does not satisfy the given question the it is a subset.

Answer 2

the AUB IS the set A which is (1 3 9 11 13) because B is subset to A

As subsets is a part of a larger group of related things foe example use 2 statements A and B now

the EMPTY SET the empty set is the unique set having no elements; its size or cardinality is zero

Example Let A = {x : 9 < x < 10, x is a natural number} will be a null set because there is NO natural number between numbers 9 and 10.
