Respuesta :
The total number of different large pizzas is 870
How many different combinations are there?
First, we need to identify the selections, and then the number of options for each of these selections.
Here we have two selections:
- First topping.
- Second topping.
Such that the options are:
- First topping: 30 options.
- Second topping: 29 options (because one was already selected and we can't repeat).
The total number of combinations is given by the product between the numbers of options, we will have:
C = 30*29 = 870
