Question

19.If A= {b,c,e,g,h}, B={a,c,d,g,j} and c={a,d,e,g,h}then show that A-(B ∩ C) = (A-B) U (A-C)


explain please one by one now i have exam plz help ​

Answer 1

Step-by-step explanation:

A= {b,c,e,g,h},

(B ∩ C) = { a, d,g}

LHS = A - (B ∩ C)

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

= {b, c,e,,h}

(A-B) ={ b,e,,h}

(A-C) ={b,c}

RHS = (A-B) U (A-C)

={ b,e,h} U {b,c}

={ b,c,e,h}

A-(B ∩ C) = (A-B) U (A-C)

{ b,c,e,h} = { b,c,e,h}

LHS = RHS

Hence proved
