Answer:
Hence, the probability of an access code “1234”=
Step-by-step explanation:
<em>" The probability of an event is defined as the ratio of total number of favourable outcomes to the total number of possible outcomes ".</em>
A bank requires a four-digit access code for each account. The access code is generated using the digits 0–9, and the digits can be repeated.
The total number of outcomes possible are 10×10×10×10=10000
since the first place any of the 10 digits are possible, similarly for the second, third and fourth place.
Also each code is a unique representation in itself.
Hence the code "1234" is unique.
Hence, the probability of an access code “1234”=
