2.Relations and Functions
easy
જો $A = \{ a,\,b\} ,\,B = \{ c,\,d\} ,\,C = \{ d,\,e\} ,\,$તો $\{ (a,\,c),\,(a,\,d),\,(a,\,e),\,(b,\,c),\,(b,\,d),\,(b,\,e)\} $ એ . . . . . બરાબર છે.
A
$A \cap (B \cup C)$
B
$A \cup (B \cap C)$
C
$A × (B \cup C)$
D
$A × (B \cap C)$
Solution
(c) $B \cup C = \{c, d\} \cup \{d, e\} = \{c, d, e\}$
$\therefore A × (B \cup C) = {a, b} × {c, d, e}$
$= {(a, c), (a, d), (a, e), (b, c), (b, d), (b, e)}.$
