Answer:
1/2600 = 0.00038
Step-by-step explanation:
To find this probability, we first need to find how many ways we can fill each letter and each digit.
The letter has 26 different values, and each digit has 10 different values, so to find the total number of passwords, we just need to multiply the possibilities for each letter and digit:
Total cases = 26 * 10 * 10 = 2600
So the probability of correctly guessing is 1/2600 = 0.00038
