Answer 1

Answer:

Step-by-step explanation:

A opposite / B = A-B

A opposite / C = A-C

Hence, A = {10,15,20,25,30,35,40,45,50}

B = {1,5,10,15,20,30}

C = {7,8,15,20,35,45,48}

A opposite/ (B∩C) = A - (B∩C) = A - {15,20}

= {10,25,30,35,40,45,50}

(A-B)∪(A-C) = {25,35,40,45,50} ∪ {10,25,30,40,50}

= {10,25,30,35,40,45,50}

so, A-(B∩C) = (A-B)∪(A-C)
