Problem

If $A$, $B$, and $C$ are cities
If there are 4 roads from $(A \Longrightarrow B)$ and 3 from
$B \Longrightarrow C$, how
many ways are there from $A \Longrightarrow C$? (Assume that
all roads are one-way, in the direction of the arrows.)

If, in addition, there are 6 roads from $C\Longrightarrow D$, how many
ways from $A \Longrightarrow D$?

As in the problem above, but 4($A\Longrightarrow B$),
3($B\Longrightarrow C$), 5($A\Longrightarrow D$), 5($D\Longrightarrow C$). How many ways from $A \Longrightarrow C$?
