A company produces a laptop whose life (without any breakdown) has a normal distribution with mean equal to 60 months and standard deviation equal to 15 months. The company wants to advertise full replacement for each unit experiencing any breakdown within the first three years.

Find the percent of units that the company would expect tor replace. Would using the normal distribution would be advantageous for the company? Why or why not? What are some ethical ramifications of designing products using information based on the normal distribution?
