A-B​

Answer 1

Answer:

[2,4]

Step-by-step explanation:

A-B = [1,2,3,4,5]-[1,3,5]

=[2,4]

Answer 2

Answer:

A - B = { 2, 4 }

Step-by-step explanation:

Given :- A = { 1, 2, 3, 4, 5 } and B = { 1, 3, 5 }

To find :- Difference of sets that is A - B

Solution :-

A and B are two sets.

A = { 1, 2, 3, 4, 5 } and B = { 1, 3, 5 }

A - B is the set of all elements that are in A but NOT present in B, and B - A is the set of all elements that are present in B but NOT in A. A - B is always a subset of A and B - A is always a subset of B.

DIFFERENCE of two sets is by taking every element that is present in the 1st set but not in the 2nd set and putting all of these elements together into one set.

∴ A - B = { 2, 4 }, since 2 and 4 are present in set A but not in B.

Therefore, A - B = { 2, 4 }
