Question

If A = {2, 3, 5}, B = {2, 5, 6}, then find (A – B) × (A ∩ B).

Answer 1

Given A = { 2,3,5 } and B = { 2,5,6 }

i)A - B = { 2,3,5 } - { 2,5,6 } = { 3 }

$ii) A \cap B = \{ 2,3,5\} \cap \{ 2,5,6 \}$

$= \{ 2,5 \}$

$Now, ( A-B) \times ( A \cap B )$

$= \{ 3 \} \times \{ 2,5 \}$

$= \{ ( 3,2) , (3,5) \}$

Therefore.,

$\red{ Value \: of \: ( A-B) \times ( A \cap B ) }$

$\green {= \{ ( 3,2) , (3,5) \} }$
