Based on data collected over several years, the time to complete servicing an electronic product ESP under warranty is assumed to be normally distributed with a mean of 32 minutes and 15 seconds, and a standard deviation of 5 minutes and 15 seconds. If two ESP products serviced by 2 tech-staff (TECH1 and TECH2) are randomly selected, find the probability that TECH1 serviced the product in at most 31 minutes and 30 seconds, and TECH2 took at least 3 minutes longer time than TECH1 to complete servicing the product.
