## How many combinations of 3 numbers can 6 numbers make?

There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6. 720 / 6 = 120.

**How many combinations are possible with 6 numbers?**

720 different

For any group of 6 numbers and letters, there are a possible 720 different permutations or combinations that can be made.

**What are the possible combinations of 3 numbers?**

There are 3 x 2 x 1 = 6 ways to arrange the three digits. In the set of 720 possibilities, each combination of three digits is represented six times.

### How many combinations of 3 numbers can you make with 5 numbers?

10 possible combinations

So 5 choose 3 = 10 possible combinations. However, there’s a shortcut to finding 5 choose 3. The combinations formula is: nCr = n! / ((n – r)!

**How many combinations can you have with 3 numbers?**

There are 3 x 2 x 1 = 6 ways to arrange the three digits. In the set of 720 possibilities, each combination of three digits is represented six times. So let’s just divide by 6.

**How many numbers can be formed using 3 digits?**

Question 8 The different 3-digit numbers which can be formed by using the digits 0, 2, 5 without repeating any digit in the number are 205, 250, 502 and 520. Therefore, four 3 digit numbers can be formed by using the digits 0, 2, 5.

#### How many combinations of 3 numbers are there?

**How do you calculate the number of combinations?**

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. To find the probability of an event, you may have to find the combinations.

**How many combinations can you make with six digits?**

It’s the same as possibilities to a 6 digit code with known numbers and no repeats. With 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don’t repeat the same item. So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items.

## How do you calculate total number of combinations?

Combination Calculator. In finite mathematics a combination is most typically calculated using the formula C(n,r) = n!/r!(n-r)!. In this formula n represents the total number of items and r represents the number of items to choose. The formula is modified depending on the importance of item order and repeating items in the set of allowed results.

**How to calculate all possible combinations?**

you can use the same item more than once.

**What is the formula for the number of possible combinations?**

The formula for combinations is generally n! / (r! (n — r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.
