well, this is my password for something. it has the probability of all the numbers from 0-9, and can only be put into combinations of four. can anyone give me all the possible combinations, i don't care how long this is going to take me to enter. i will stay up all week. any help is appreciated.
(example: one combination could be 1289)

10,000 possibilities:
Just start at 0000, and keep counting....
(0001, 0002, 0003, etc.)

ok let me give you similar example using the lottery. Daily numbers are 4 digits and can all repeat so easily that is from 0000 to 9999. that is 10,000. if yours can all repeat as show 10,000 is your answer. However if that is not the case you have to use a little bit of division and cross elimination of numbers. on top 0 thru 9 is 10 numbers possible but only in groups of 4. you take 10 x 9 x 8 x 7. on bottom you have 1 x 2 x 3 x 4. if you were using a group of 5 for ex top would go to 6 and bottom to 5. you write the 10 thru 7 over 1 through 4 as a division example. simplify all numbers. 2,3,4 all simplify to 1 and 10 goes to 5, 9 goes to 3, 8 goes to 2. Leaving you with 5 x 3 x 2 x 7 as top of the fraction over 1 which is itself. take 5 x 3 x 2 x 7 and you get 210. That is why if you ever look at www.rilot.com for a 4 digit number all different digits it pays you 208 so its not even money. I looked this up way back as just for kicks. Any other questions email me if you want m_lavallee@cox.net or IM me at niceguyswthrt on Yahoo IM anytime.

for each digit you have 10 possible numbers: 10 x 10 x 10 x 10 or 10,000 possible outcomes.
Think of it this way, the largest number you could make with 4 digits is 9,999 plus you have 0000 which would be 10K combinations.

Start off with the four zeros and work your way up through the numbers to the four nines, that is, there are 10,000 possibilities.

The bank won't let you have that many attempts.
