The number of proper subsets of the set $\{1, 2, 3\}$ is

Which of the following is a subset of every set?

If $A = \{1, 2, 3, 4, 5, 6\}$, then which of the following statements is not true?

Write the following as intervals: $\{x : x \in \mathbb{R}, 0 \le x < 7\}$

Two dice are thrown. The events $A, B$ and $C$ are as follows:
$A:$ getting an even number on the first die.
$B:$ getting an odd number on the first die.
$C:$ getting the sum of the numbers on the dice $\leq 5$.
Describe the event $A$ or $B$.

Examine whether the following statement is true or false:
$\{x : x \text{ is an even natural number less than } 6\} \subset \{x : x \text{ is a natural number which divides } 36\}$
