Using it's concept, it is found that there is a [tex]\frac{1}{10000}[/tex] probability of an access code "1234".
A probability is given by the number of desired outcomes divided by the number of total outcomes.
Considering that each digit has 10 possible outcomes, and there are 4 digits, the total number of outcomes is given by:
[tex]T = 10^4 = 10000[/tex].
1234 is only one access code, hence the probability is given by:
[tex]p = \frac{1}{10000}[/tex]
