Final answer:
The probability that someone other than the owner can unlock a phone with biometrics requires data on the system's false acceptance rate and the number of unauthorized attempts, which is not provided; hence the question cannot be accurately answered.
Step-by-step explanation:
The probability that someone who is able to unlock the phone using the biometric security feature is not the owner is not provided in the given information. To answer this question, one would need data on the accuracy of the biometric system or the rate of false positives (times when a non-owner is incorrectly recognized as the owner), as well as how many unauthorized attempts are made. Since the specific probability is not provided in the context of this question and cannot be determined from the information given, a factually accurate answer cannot be provided.
To calculate such a probability in general, one would use information such as the false acceptance rate (FAR) of a biometric system, which measures how often unauthorized persons are incorrectly accepted. But without this or related data, it is not possible to compute the probability.
