Project 11: iPhone Battery

Project 11:  John bought an iPhone 3 years ago and the battery died today.  John wants to determine the number of iPhones bought at the same time he purchased his that have died already.

Facts:

iPhone sells roughly 90 million iPhones per month.  We will assume that 90 million iPhones were sold in the same month that John purchased his.

The time (in years) before an iPhone battery dies is normally distributed with mean 'meanLife' and standard deviation 'sdLife'.  

Task: Implement code to appropriately initialize the value of 'numberDead' that represents the number of iPhones purchased the same month as John that have already died.
