यदि $A = \{ a,\,b\} ,\,B = \{ c,\,d\} ,\,C = \{ d,\,e\} ,\,$ तब $\{ (a,\,c),\,(a,\,d),\,(a,\,e),\,(b,\,c),\,(b,\,d),\,(b,\,e)\} $ बराबर है

A

$A \cap  (B \cup C)$

B

$A \cup (B \cap  C)$

C

$A × (B \cup C)$

D

$A × (B \cap  C)$

Solution

$B \cup  C = \{c, d\} \cup  (d, e\} = {c, d, e}$

$\therefore $ $A × (B \cup  C) = \{a, b\} × \{c, d, e\} = \{(a, c), (a, d), (a, e), (b, c), (b, d), (b, e)\}.$
