The number of different combinations of these items that you can make if you choose four (4) toppings is equal to 1.
<h3>How to calculate the combinations of these items.</h3>
In order to determine the combinations of these items that this person can make, we would use this mathematical model known as combination.
Mathematically, combination is calculated by using this mathematical equation:
![_nC_r = \frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=_nC_r%20%3D%20%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
<u>Where:</u>
- n is the total number of items.
- r is the number of times of choosing items.
<u>Given the following data:</u>
Let us assume you'll choose four (4) toppings.
Substituting the given parameters into the formula, we have;
⁴C₄ = 4/4
⁴C₄ = 1.
