how many 4 number combinations are possible?
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.

['Answer: There are 9,999 different combinations in a 4-digit lock.', 'Explanation: The 4-digit number on a lock begins from 0000 and ends up to 9999 which are:', 'From 0000 to 0999 there are 999 combinations. ( ... ', 'From 1,000 to 9,999 there are 8,999 combinations (9,000)', 'And now we have 1,000+9,000=10,000 combinations total.']

For each of these 4 first choices there are 3 second choices. Therefore there are 4 x 3 = 12 possibilities.

2! See for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist number and next two are repeated from 10 numbers hence 10!/2! So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!

The number of possible combinations with 4 numbers without repetition is 15.

With three total inputs, how many different input combinations can you make? 8! This number grows exponentially at 2n, where n is the number of inputs. So, a 4-input AND gate has 16 possible combinations, 5 inputs would be 32 outputs, and so on.

There are 1 billion 9 digit numbers (000,000,000 through 999,999,999). There are 45 different combinations of two different numerals (10 x 9 divided by 2). There are 512 (2 to the 9th power) different permutations for any two numbers to be used in a 9 digit number. 45 x 512 = 23,040 - 10 = 23,030.

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.

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.

With respect to that technical meaning, there is only one combination of the four numbers 4, 5, 8, and 7, taken four at a time: All four of them. There are 24 combinations. 4578, 4587, 4758, 4785, 4857, 4875, 5478, 5487, 5748, 5784, 5847, 5874, 7458, 7485, 7548, 7584, 7845, 7854, 8457, 8475, 8547, 8574, 8745, and 8754.

First, we have six possible digits to use to form our number. Assuming we can reuse any of these, the answer is simply 6^4, or 1,296 possible combinations.

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.

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.

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.
