What does the generator do?
The generator alternates between three scenarios — T-shirts, pizzas, sandwiches. Each time it picks a small number of options in each group (2 or 3) and draws a tree diagram.
How to solve
The tree has two levels. For every choice in the first group there is the same number of branches in the second group. The total number of combinations is the number of options in the first group times the number in the second. The tree has exactly that many leaves.
