Remember, the formula to calculate combinations is nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.
How many combinations are possible in a lock?
FACT: most masterlock padlocks have around 64,000 possible combinations. ANOTHER FACT: this instructable ( if done properly) will turn 64,000 into 100.

How many combinations are there to a 3 digit lock?
By comparison, this 3-dial lock (three wheels, each with digits 0-9) has 10 ? 10 ? 10 = 1, 000 possible combinations.
How do you find all 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. We want to select 13 cards, so r = 13.
How many combinations of 2 numbers are there?
So that means you need to know how many different permutations there are for each combination. If there are two numbers, there are two permutations per combination. Divide the possible permutations by number of permutations per combination: 2450 / 2 = 1225.
How do you make all possible 4 digit combinations?
In Excel, you can use below formula to list all possible 4 digits combinations of number 0 to 9. Select a blank cell and type this formula =TEXT(ROW(A1)-1,”0000″) into it, and press Enter key, then drag the autofill handle down until all the 4 digits combinations are listing.
How long does it take to crack a 4 digit PIN?
It would take up to 112 hours to brute force a 4 digit PIN, because each PIN entry takes 40 seconds.

How many combinations are there with 3 letters and 3 numbers?
The total number of arrangements of three letters followed by three digits is then the product of the number of options available at each step and is then 26?26?26?10?10?10=263?103.
How many combinations of 60 numbers are there?
10 10 10 = 1000 three digit combinations. There are 60 of them. Using the same argument as above there are 60 60 = 3600 two “digit” combinations and 60 60 60 = 216000 three “digit” combinations.
How many combinations of 3 items are there?
3*3*3=27 unique possibilities.
How do you generate all possible combinations of one list?
To create the list of all possible combinations:
- Click the Expand button in the column header. From the sub-menu: Select only the column with the data we wish to retain (i.e., in our example, uncheck the Temp column)
- The list of possible combinations now appears in the Power Query window.

How many combinations can you make with 3 numbers without repeating?
If what you want are all possible three digit numbers with no repetition of the digits then you have 10 choices for the first digit, you have 9 choices for the 2nd digit, and you have 8 choices for the 3rd digit giving you 10x9x8 = 720 in all.
How many combinations of 4 items are there?
I.e. there are 4 objects, so the total number of possible combinations that they can be arranged in is 4! = 4 x 3 x 2 x 1 = 24.
How many combinations of 5 items are there?
120 ways
Note that your choice of 5 objects can take any order whatsoever, because your choice each time can be any of the remaining objects. So we say that there are 5 factorial = 5! = 5x4x3x2x1 = 120 ways to arrange five objects. In general we say that there are n!
How many ways can you arrange 3 things?
6 ways
Factorial Formula
Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! = 3*2*1 = 6 ways.
How many combinations of 1234 are there?
If we are looking at the number of numbers we can create using the numbers 1, 2, 3, and 4, we can calculate that the following way: for each digit (thousands, hundreds, tens, ones), we have 4 choices of numbers. And so we can create 4?4?4?4=44=256 numbers.
