Also know, what are all the possible combinations of 1234?

If you wager on **1234** boxed, you would win ifanyof the following **combinations** were drawn: **1234**,1243,1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 2431,3124,3142, 3214, 3241, 3412, 3421, 4123, 4132, 4213, 4231, 4312,or4321.

Beside above, how many combinations are there for a 3 digit lock? Depends on the numbering system.Withbase 10 (i.e. zero to nine), there would be 10 x 10 x 10 =1000**combinations**. A brute force attack can simply be usedtofind **combination**.

In this way, how many combinations are there in a 5 digit lock?

Thus you have made **5** × 4 × 3 ×21 = 120 choices and there are 120 possible **5 digit**numbersmade from 1, 2, 3, 4 and **5** if you don't allowany**digit** to be repeated. Now consider the possibilities with13as the first two **digits**.
