Question

B-A=? is set formula​

Answer 1

Answer:

The difference of set B from set A, denoted by A-B, is the set of all the elements of set A that are not in set B. In mathematical term, A-B = { x: x∈A and x∉B} If (A∩B) is the intersection between two sets A and B then, A-B = A - (A∩B)

Answer 2

Complete question:

Give the formula for the set B-A

Answer:

B -A = {x:x/x ∈B and x∉A}

Step-by-step explanation:

To find,

The formula for the set B-A

Solution

Let A and B are any two sets

Then, sets A-B and B -A represents the difference of sets A and B

Here, the set B -A is defined as the set of all elements in set B, which are not the elements in set A

That is, B -A = {x:x/x ∈B and x∉A}

As an example, if we consider set B as the set of all-natural numbers and set A as the set of all odd numbers,

then B -A  is the set of all-natural numbers which are not odd numbers

that is B -A is the set of all even numbers
