Question

if A={2,4,6,8,10}andB={3,6,9,12,15} find A-B andB-A​

Answer 1

Answer:

A - B = { 2 , 4 , 8 , 10 }

B - A = { 3 , 9 , 12 , 15 }

Step-by-step explanation:

A - B refers to those elements which belong to A but don't belong to B.

In the same manner, B - A refers to those elements which belong to B but don't belong to A.

Here,

A - B has all the elements which are from A but not from B.

Elements from A : 2 , 4 , 6 , 8 , 10

Now removing the elements which also belong to B, here, that's 6 only.

So,

A - B = { 2 , 4 , 8 , 10 }

Similarly,

B - A should have elements from B who don't belong to A.

elements of B : 3 , 6 , 9 , 12 , 15

Now, removing the elements which belong to A, here that's 6 only.

B - A = { 3 , 9 , 12 , 15 }

Answer 2

Answer:

Given,

A={2,4,6,8,10}

B={3,6,9,12,15}

A-B=The elements of A which are not in B

B-A=The elements of B which are not in A

Here,

A-B={2,4,8,10}

B-A={3,9,12,15}
