TABLE 3:1. EXPECTANCY AND REMAINING VALUE OF ANY 
ARTICLE WHOSE REPLACEMENT COST IS $100 
All values in this table are based on the assumption that in a group of 
many articles, no article will survive twice its probable life and that the 
number of annual failures will increase at a uniform rate to a maximum 
at the end of the probable life term and will thereupon decrease at a uni- 
form rate.
