The sub shop has

6
6 different kinds of bread,
4
4 types of cheese,
3
3 types of meat,
6
6 vegetable toppings and
9
9 types of sauce. Assuming you will pick exactly one of each how many different possibilities are there?

To calculate the number of different possibilities, we multiply the number of options for each category:

Number of bread options: 6
Number of cheese options: 4
Number of meat options: 3
Number of vegetable toppings options: 6
Number of sauce options: 9

Combining these options, we have:

6 x 4 x 3 x 6 x 9 = 3888

Therefore, there are 3888 different possibilities for the sub shop.
