How do you explain a combination?
What is a Combination? A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.
What are all the possible combinations of 4 numbers 0 9?
10,000 possible combinations
Berry analyzed passwords from previously released and exposed tables and security breaches, filtering the results to just those that were exactly four digits long [0-9]. There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code.

How many mastery points in counting permutations and combinations?
Level up on all the skills in this unit and collect up to 500 Mastery points! This unit covers methods for counting how many possible outcomes there are in various situations. We’ll learn about factorial, permutations, and combinations. We’ll also look at how to use these ideas to find probabilities.
How are combinations used to figure out exponents?
If you’re clever, you realize you can use combinations and permutations to figure out the exponents rather than having to multiply out the whole equation. This is what the binomial theorem does.
Which is the correct order for a combination lock?
A true “combination lock” would accept both 10-17-23 and 23-17-10 as correct. Let’s start with permutations, or all possible ways of doing something. We’re using the fancy-pants term “permutation”, so we’re going to care about every last detail, including the order of each item.
