Can you conclude that a-B if A and B are two sets?

Can you conclude that a-B if A and B are two sets?

Yes. Since A is in the power set of B, A is a subset of B. Likewise, B is a subset of A. Therefore, A = B.

What can you say about the sets A and B if AB BA?

and A – B = B – A , if A = B. Therefore ,we can say that the each element of set A belong to the every element of set B.

Can you conclude that a B if A and B are two sets with the same power sets why?

Similarly, ∀ Y ⊂ B, we can prove that Y ⊂ A. Thus, every subset of A is a subset of B and every subset of B is a subset of A.

How many elements are there in AXB If A has m elements and B has n elements?

To explain: If set A has m elements and set B has n elements then A X B has m*n elements. We know, a set has 2^r subsets if it has r number of elements. Here, A X B has 2*3 = 6 elements.

What is the relationship of a-B and B-A?

Definition 1. Let A and B be sets. A relation from A to B is a set of ordered pairs (a, b) such that a ∈ A and b ∈ B. In other words, a relation from A to B is a subset of A × B.

What is the answer of AB BA?

Yes, you are correct. a=b implies that a-b = b-a.

Is a B is equal to B-A?

Step-by-step explanation: The equality between A and B is written A = B, and pronounced A equals B. The word “commutative” comes from “commute” or “move around”, so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is “a + b = b + a”; in numbers, this means 2 + 3 = 3 + 2.

What does set a B mean?

The set A−B consists of elements that are in A but not in B. For example if A={1,2,3} and B={3,5}, then A−B={1,2}. In Figure 1.8, A−B is shown by the shaded area using a Venn diagram. Note that A−B=A∩Bc.

How do you prove A and B are two sets?

1.Suppose A, B are two sets. Prove the statement : If A-B=B-A, then A=B. By definition of sets, since there can only be one of the same element in a set A U A =A. Therefore, So A=B. –> iS THIS A CORRECT PROOF?

What if A and B are two subsets of U?

What do the sets A and B have in common?

Theintersection of A and B,writtenA\\B,istheset of all elements that belong to both A and B. This is what the two sets have in common. Below is a venn diagram illustrating the set A\\B.
