how many possible combinations of four numbers?
16574
Thus you have 10x10x10 = 1000 choices for the first three digits. Finally you have 10 choices for the fourth digit and thus there are 10x10x10x10 = 10 000 possible 4 digit combinations from 0-9.

Thus you have made 5 × 4 × 3 × 2 1 = 120 choices and there are 120 possible 5 digit numbers made from 1, 2, 3, 4 and 5 if you don't allow any digit to be repeated. Now consider the possibilities with 13 as the first two digits.

Explanation: 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.
1425827
It also means that when we selected one item (four choices), we created four different combinations with three items. Now we now all of the combinations and can add them up: 1 + 4 + 6 + 1 + 4 = 16 different possibilities.

To find the number of permutations it is all about choices. You know the 4 digits, but you don't know the order. So this is 4 × 3 × 2 × 1 = 24, if all 4 digits are different.

there are 64,000 possible combinations on a standard 40-number Master Lock. With this method, however, you can quickly narrow that down to 100 combinations, a workable number to try if you've got the time and the inclination to give it a shot.

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N.
295474
Given 100, choose 99, there are 100 combinations. Given 100, choose 98, there are 161,700 combinations. The number of combinations gets bigger fast. 100, choose 95, is over 7 million combinations.
225114
There are two possible values for each switch. As there are 4 switches , the total number of permutations or unique combinations are 2^4=16.
1166886
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.
1031102
Answer and Explanation: The number of possible 16-digit combinations, where repetition is allowed is 10,000,000,000,000,000.

4 CHOOSE 2 = 6 possible combinations. 6 is the total number of all possible combinations for choosing 2 elements at a time from 4 distinct elements without considering the order of elements in statistics & probability surveys or experiments.

By dividing a binary number up into groups of 4 bits, each group or set of 4 digits can now have a possible value of between “0000” (0) and “1111” ( 8+4+2+1 = 15 ) giving a total of 16 different number combinations from 0 to 15.
858414
1 + 4 + 6 + 1 + 4 = 16 different possibilities. A related topic to combinations is "permutations". When order matters, you use permutations because combinations consider order to be irrelevant ( a, b is the same as b, a).
1374971
If you allow repetitions of any digit, then there are 4 choices for each of the 3 positions in the 3-digit numbers, or 4 x 4 x 4 = 64 3-digit numbers, in total.
903955
6 x 5 x 4 x 3 = 360 possible combinations. Given a 4 digit integer. each digit can be 1 through 6. No two digits the same.
