The sub shop has
6
6 different kinds of bread,
6
6 types of cheese,
3
3 types of meat,
4
4 vegetable toppings and
10
10 types of sauce. Assuming you will pick exactly one of each how many different possibilities are there?
The total number of possibilities can be calculated by multiplying the number of choices for each category:
6 (bread) x 6 (cheese) x 3 (meat) x 4 (vegetable toppings) x 10 (sauce) = 4320
Therefore, there are 4320 different possibilities when choosing one of each item from the sub shop.
