Mizoram Board Solutions for Chapter: Sets, Exercise 4: EXERCISE 1.4

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$\}$, then which set is equal to $A\cap C$?

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 $\}$, then, $A\cap D$ is same as which set?

If $X=\left\{a,b,c,d\right\}$ and $Y=\left\{f,b,d,g\right\},$ find $X\cap Y$.

If $R$ is the set of real numbers and $Q$ is the set of rational numbers, then what is $R-Q?$

$\{2, 3, 4, 5\}$ and $\{3, 6, 7, 9, 10\}$ are not disjoint sets.

$\{a, e, i, o, u\}$ and $\{a, b, c, d\}$ are disjoint sets.

$\{2, 6, 10, 14\}$ and $\{3, 7, 11, 15\}$ are disjoint sets.

$\{2, 6, 10\}$ and $\{3, 7, 11\}$ are disjoint sets.
