1.Set Theory
easy
मान लीजिए कि $A =\{a, e, i, o, u\}$ और $B =\{a, i, u\} .$ दर्शाइए कि $A \cup B=A$
Option A
Option B
Option C
Option D
Solution
We have, $A \cup B=\{a, e, i, o, u\}=A$
This example illustrates that union of sets $A$ and its subset $B$ is the set $A$ itself, i.e., if $B \subset A ,$ then $A \cup B = A$
