Question

write any two sets A and B such that both A and B are disjoint. Find A-B and B-A.

Answer 1

Heya!

Here is yr answer.....


The two sets are -----

A = { a , b, c, d }

B = { e, f, g, h }

_____________________________

A-B = {a, b, c, d} - {e, f, g, h}

A-B = {a,b,c,d}

_____________________________

B-A = {e, f, g, h}-{a, b, c, d}

B-A = {e, f, g, h}


Note :
~~~~

If A, B are any two disjoint sets.... then

A-B = A

B-A = B

Answer 2

Step-by-step explanation:

Let the sets are A = {1,2,3,4} and B= {5,6,7,8}

A-B = {1,2,3,4} - {5,6,7,8}

= { 1,2,3,4}

B-A = {5,6,7,8} - {1,2,3,4}

= { 5,6,7,8}

AnB= { 1,2,3,4} n {5,6,7,8}

= { }

( therefore A-B, B-A and AnB are disjoint sets
