easy
मान लीजिए कि $A =\{1,2,3\}, B =\{3,4\}$ और $C =\{4,5,6\} .$ निम्नलिखित ज्ञात कीजिए
$( A \times B ) \cup( A \times C )$
Option A
Option B
Option C
Option D
Solution
Using the sets $A \times B$ and $A \times C$ from part $(ii)$ above, we obtain
$(A \times B) \cap(A \times C)=\{(1,4),(2,4),(3,4)\}$
$(A \times B) \cup(A \times C)=\{(1,3),(1,4),(1,5),(1,6),(2,3),(2,4),(2,5),(2,6)$
$(3,3),(3,4),(3,5),(3,6)\}$
