Question

Find the symmetric difference between the following sets. (i) X=(5,6,7) and Y=(5,7,9,10)​

Answer 1

Answer:

Step-by-step explanation:

Hi ,

****************************************

Symmetric Difference :

Let A and B are two sets.

Symmetric Difference of A and B

( A ∆ B ) = ( A - B ) U ( B - A )

*******************************************

Here ,

X = { 5 , 6 , 7 } and Y = { 5,7 9,10 }

i ) X - Y = {5,6,7} - {5,7,9,10}= { 6 }

ii ) Y - X = { 5,7,9,10 } - {5,6,7} = {9,10}

____________________

X ∆ Y = ( X - Y ) U ( Y - X )

= { 6 } U { 9 , 10 }

= { 6, 9 , 10 }

I hope this helps you.
