1.Set Theory
easy
આપેલ સંબંધ જુઓ :
$(1) \,\,\,A - B = A - (A \cap B)$
$(2) \,\,\,A = (A \cap B) \cup (A - B)$
$(3) \,\,\,A - (B \cup C) = (A - B) \cup (A - C)$
પૈકી . . . . સત્ય છે.
A
$1$ અને $3$
B
માત્ર $2$
C
$2$ અને $3$
D
$1$ અને $ 2$
Solution
(d) $A – B = A – (A \cap B)$ is correct.
$A = (A \cap B) \cup (A – B)$ is correct.
$(3)$ is false.
$\therefore (1)$ and $(2) $ are true.
