Determine whether the following set is finite or infinite:
$\{1, 2, 3, \ldots\}$

Let $A = \{1, 2, 3, 4, 5, 6\}$. Insert the appropriate symbol $\in$ or $\notin$ in the blank space:
$10 \dots A$

Consider the experiment of rolling a die. Let $A$ be the event 'getting a prime number' and $B$ be the event 'getting an odd number'. Write the sets representing the events $A$ and $B$.

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

If $A, B,$ and $C$ are three sets,then $A \cap (B \cup C) =$

In the following,state whether $A = B$ or not:
$A = \{2, 4, 6, 8, 10\}$; $B = \{x : x \text{ is a positive even integer and } x \le 10\}$
