A financial institution is implementing a Security Information and Event Management (SIEM) system to enhance its security operations. The security team is tasked with configuring the SIEM to detect potential insider threats. They decide to monitor user behavior analytics (UBA) and set thresholds for unusual activities, such as accessing sensitive data outside of normal working hours. If a user accesses sensitive data more than 5 times within a 24-hour period, an alert should be triggered. Given that the average number of sensitive data accesses per user per day is 3, with a standard deviation of 1, what is the probability that a randomly selected user will trigger an alert based on the normal distribution? Assume the distribution of accesses follows a normal distribution.
