MCQ
Which of the following statement is false (where $A$ $\&$ $B$ are two non empty sets)
  • A
    $A - B = A \cap B'$
  • B
    $A - B = A - (A \cap B)$
  • $A - B = A - B'$
  • D
    $A - B = (A \cup B) - B$

Answer

Correct option: C.
$A - B = A - B'$
c
$A  \cap B' = A - (A  \cap B)$
$A  \cap B' = (A \cup B) - B$
