Answer:

12

Step-by-step explanation:

[tex]n_{C} r = \frac{n!}{(n-r)!(r!)} \\\\[/tex]

n is the number of choices

r is the number of Selections we can make

For Sandwiches:

3 Choices w/ 1 Selections

[tex]n = 3\\r = 1\\[/tex]

[tex]n_{C} r = \frac{3!}{(3-1)!(1!)} = 3[/tex]

For Veg.:

2 Choices w/ 1 Selections

[tex]n = 2\\r = 1\\[/tex]

[tex]n_{C} r = \frac{2!}{(2-1)!(1!)} = 2[/tex]

For Dessert.:

2 Choices w/ 1 Selections

[tex]n = 2\\r = 1\\[/tex]

[tex]n_{C} r = \frac{2!}{(2-1)!(1!)} = 2[/tex]

Multiply All Combinations ∴

[tex]3 * 2 * 2 = 12[/tex]
