Answer: 560

Step-by-step explanation:

We know that the combination of n things taken x things at a time is given by :-

[tex]^nC_x=\dfrac{n!}{x!(n-x)!}[/tex]

Now, the number of different 3-topping combinations can a customers choose from 16 combination is given by :-

[tex]^{16}C_3=\dfrac{16!}{3!(16-3)!}\\\\=\dfrac{16\times15\times14\times13!}{3!13!}=560[/tex]

Hence, the number different 3-topping combinations can a customers choose from 16 combination = 560
