combinations

Combinations refer to selecting a group of items from a larger set where the order of selection doesn’t matter. For example, choosing 3 flavors of ice cream from 10 options involves combinations. It’s about the variety you can create without emphasizing the order, unlike arrangements or permutations. Combinations are useful in determining possible groupings in situations like lottery ticket picks, team selections, or selecting toppings. Mathematically, the number of combinations depends on how many items you choose and the total items available, and it’s calculated using a formula that accounts for all possible unique groupings.
