Find the union of each of the following pairs of sets :
$X =\{1,3,5\} \quad Y =\{1,2,3\}$
$\{ 1,2,3,5\} $
$X=\{1,3,5\} Y=\{1,2,3\}$
$X \cup Y=\{1,2,3,5\}$
Let $A$ and $B$ be subsets of a set $X$. Then
If $A=\{3,6,9,12,15,18,21\}, B=\{4,8,12,16,20\},$ $C=\{2,4,6,8,10,12,14,16\}, D=\{5,10,15,20\} ;$ find
$C-B$
If $X$ and $Y$ are two sets such that $X$ has $40$ elements, $X \cup Y$ has $60$ elements and $X$ $\cap\, Y$ has $10$ elements, how many elements does $Y$ have?
If $A = \{ x:x$ is a natural number $\} ,B = \{ x:x$ is an even natural number $\} $ $C = \{ x:x$ is an odd natural number $\} $ and $D = \{ x:x$ is a prime number $\} ,$ find
$B \cap D$
Which of the following pairs of sets are disjoint
$\{a, e, i, o, u\}$ and $\{c, d, e, f\}$
