To verify that if we search, for example, 3 prefixes (hex), we can skip the probability for the space of 2 prefixes '256' when we find an 'abc'. Clearly, in the space of the next 256, the probabilities of finding 'abc' are minimal. That's why my method searches in the most probable zones first and then, if necessary, reduces the percentage in the database to continue exploring without retracing steps, but always focusing on the most probable place.

Is it so difficult for AI experts to do this?:

Code:
import secrets

def generate_hex():
    return ''.join(secrets.choice('0123456789abcdef') for _ in range(2))

def calculate_probabilities(attempts):
    count_ab = 0
    count_abc = 0
   
    for _ in range(attempts):
        hex_val = generate_hex()
        if "ab" in hex_val:
            count_ab += 1
        if "abc" in hex_val:
            count_abc += 1
   
    probability_ab = count_ab / attempts
    probability_abc = count_abc / attempts
   
    return probability_ab, probability_abc

attempts = 256
samples = 1000
sum_probability_ab = 0
sum_probability_abc = 0

for _ in range(samples):
    probability_ab, probability_abc = calculate_probabilities(attempts)
    sum_probability_ab += probability_ab
    sum_probability_abc += probability_abc

average_probability_ab = sum_probability_ab / samples
average_probability_abc = sum_probability_abc / samples

print(f"Average probability of finding 'ab' in {attempts} attempts (based on {samples} samples): {average_probability_ab:.6f}")
print(f"Average probability of finding 'abc' in {attempts} attempts (based on {samples} samples): {average_probability_abc:.6f}")
