title: sum of minterm vs product of maxterm
body: <p>Given the following Boolean expression of F(A,B,C): F(A,B,C) = A' + B + C'
  Which of the following statements is/are true about the above expression?</p>
  
  <p>(i) It is an SOP expression
  (ii) It is a POS expression
  (iii) It is a sum-of-minterms expression
  (iv) It is a product-of-maxterms expression</p>
  
  <p>The model answer for this question is i),ii) and iv)</p>
  
  <p>My question is why is iii) not one of the answers? i drew the K-map and found out that its possible to derive such a sum-of-minters expression</p>
