Answer :

it could be a 1 out of 4096 guess that he can take inorder to get the code right

The probability of a correct guess on the first​ try is 1 / 16384.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Consider the provided information.

The ATM has 4 keypads and required a 6-digit pin, where repetition is allowed.

The thief has 6 slots and 4 choices per slot. Because repetition is allowed.

Thus, the total number of different ways are:

4×4×4×4×4×4 = 4096

The probability will be calculated as:=

P = 1 / 4096

Therefore, the probability of a correct guess on the first​ try is 1 / 4096
