Final answer:

To find the probability that someone who is able to unlock the phone using the biometric security feature is not the owner, divide the number of attempts made by someone other than the owner by the total number of attempts to unlock the phone. The probability is 0.3375 or 33.75%.

Explanation:

To find the probability that someone who is able to unlock the phone using the biometric security feature is not the owner, we need to divide the number of attempts made by someone other than the owner (1,350) by the total number of attempts to unlock the phone (4,000).

So, the probability is calculated as:

Probability = Number of attempts made by someone other than the owner / Total number of attempts to unlock the phone = 1,350 / 4,000 = 0.3375

Therefore, the probability that someone who is able to unlock the phone using the biometric security feature is not the owner is 0.3375 or 33.75%.
