To solve this problem, we will use the concept of combinations in mathematics.

1. First, we need to find out how many ways we can choose 3 toppings out of 10. This is a combination problem which can be solved using the formula for combinations: C(n, k) = n! / [k!(n-k)!], where n is the total number of options, k is the number of options to choose, and "!" denotes factorial.

So, C(10, 3) = 10! / [3!(10-3)!] = 120 ways.

2. Next, we need to find out how many ways we can choose 4 toppings out of 10. Using the same formula:

C(10, 4) = 10! / [4!(10-4)!] = 210 ways.

3. Since we can choose either 3 or 4 toppings, we add the two results together to get the total number of ways to choose toppings.

So, 120 (from step 1) + 210 (from step 2) = 330 ways.

Therefore, there are 330 ways to choose either three or four toppings from a selection of 10.
