How is working out a formula for the number of possibilities similar to working out probabilities??
You add separate cases and multiply possibilities within a case.
Let $t_n$ denote the number of possibilities for an $n$-tower. So $t_1$ means the number of possibilities for a $1$-tower and $t_2$ means the number of possibilities for a $2$-tower. Since this is recursive, how could you write a formula in terms of $t_{n-1}$, $t_{n-2}$ etc. for the number of possibilities for $t_n$??
