Which set is the subset of all given sets?

Consider the sets $\phi, A=\{1,3\}, B=\{1,5,9\}, C=\{1,3,5,7,9\}$. Insert the symbol $\subset$ or $\not\subset$ between the following pair of sets: $A \dots C$.

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

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 $B$.

If $A = \{2, 3, 4, 5, 6\}$,then which of the following statements has a truth value of 'false'?

In each of the following,determine whether the statement is true or false. If it is true,prove it. If it is false,give an example.
If $A \subset B$ and $B \subset C$,then $A \subset C$.
