Quoted By:
Our 8 digit ID is randomly generated from small a-z, capital A-Z, +, /, and number 0-9
That is to say:
26 + 26 + 2 + 10 = 64
There are only 6 patterns to get "kot" ID
kot*****
*kot****
**kot***
***kot**
****kot*
*****kot
Therefore, the probability of getting "kot" ID is
64^-8 x 6 = 2.1 x 10^-14 = 0.0000000000021%
...Is this correct?
