## How many combinations can you make with 6 items?

For any combination of items, each item is either included or not included in the combo. That means each item has 2 possibilities for every combination. For 6 items, that would make the number of combinations = 2^6 = 64.

**How many ways can you arrange 6 things?**

So the six letters can be a combination of 6×5×4×3×2×1 letters or 720 arrangements.

**How do you calculate unique combinations?**

Remember that combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

### Does order matter in finding all the possible combinations in a combination lock?

Permutations are for lists (order matters) and combinations are for groups (order doesn’t matter). You know, a “combination lock” should really be called a “permutation lock”. The order you put the numbers in matters. A true “combination lock” would accept both 10-17-23 and 23-17-10 as correct.

**How many unique numbers are there in 6 digits?**

There are 999999 – 100000 + 1 possible ways to make 6 digit numbers using the dgits 1 – 9. There are 900000 possible ways to get 6 digit numbers using 0 – 9.

**How many 6 digit number combinations are there?**

## What are unique combinations?

a leading to only one result. the sum of two integers is unique.

**How many combinations are there of six distinct objects taken three at a time?**

Using factorials, we get the same result. There are 120 ways to select 3 officers in order from a club with 6 members. We refer to this as a permutation of 6 taken 3 at a time.

**How many different combinations are there for 6 items?**

For the 5th item we have 2 possibilities so 2*3*4*5*6 =720. And for the 6 we only have one choice left after choosing the other 5 so its the same answer because 2*3*4*5*6*1=720 what do we do? We add the possibilities! 720+ 720+ 360+ 120+ 30+ 6= 1956 different combinations for 6 items.

### How many combinations can you make with a set of 3 balls?

Let’s take a simpler example where you choose three balls called R (red), B (blue), G (green). There are six permutations of this set (the order of letters determine the order of the selected balls): RBG, RGB, BRG, BGR, GRB, GBR, and the combination definition says that there is only one combination!

**How many combinations can you make with the NCR calculator?**

Every letter displayed in the nCr calculator represents a distinct color of a ball, e.g., A is red, B is yellow, C is green, and so on. If you choose only one element r = 1 at once from that set, the number of combinations will be 12 – because there are 12 different balls.

**What is the difference between combinations and permutations in math?**

Combinations vs permutations. The difference between combinations and permutationsis is that while when counting combinations we do not care about the order of the things we combine with permutations the order matters. Permuations are for ordered lists, while combinations are for unordered groups.
