Question

If Set A= { 1, 3, 5, 7, 9} and Set B = { 1, 2, 4, 6, 8} , then find Set B - A
please provide explanation

Answer 1

$\huge \sf {\orange {\underline {\pink{\underline {A᭄ɴsᴡᴇʀ࿐ :−}}}}}$

A= { 1, 3, 5, 7, 9} B = { 1, 2, 4, 6, 8}

B-A= { 1, 2, 4, 6, 8}- { 1, 3, 5, 7, 9}

B-A= {2, 4, 6, 8}

Set Difference: The relative complement or set difference of sets A and B, denoted A – B, is the set of all elements in A that are not in B. In set-builder notation, A – B = {x ∈ U : x ∈ A and x ∉ B}= A ∩ B'.
