A software company has a help line through which customers can call for technical support. Based on historical records, 50% of calls last less than 5 minutes, 40% of calls last between 5 and 15 minutes, and 10% of calls last longer than 15 minutes. Furthermore, when a call lasts less than 5 minutes, 95% of the time the customer's problem is resolved. For calls lasting between 5 and 15 minutes, 85% of the time the customer's problem is resolved. For calls lasting longer that 15 minutes, however, only 40% of the time is the customer's problem is resolved. a. b. C. Given the customer's problem was resolved, determine the probability that the call lasted for less than 5 minutes. Given the customer's problem was not resolved, determine the probability that the call lasted between 5 to 10 minutes. Given the customer's problem was resolved, determine the probability that the call lasted for 5 minutes or more.
