What is the reliability for a new mission of t = 10 hours duration, starting the new mission at the age of T = 30 hours, for the same data as [[Example: Weibull Disribution Unreliability RRX Example|Example 8]]?
 
'''Solution'''
 
The conditional reliability is given by:
 
::<math>R(t|T)=\frac{R(T+t)}{R(T)}</math>
 
or:
 
::<math>\hat{R}(10hr|30hr)=\frac{\hat{R}(10+30)}{\hat{R}(30)}=\frac{\hat{R}(40)}{\hat{R}(30)}</math>
 
 
Again, the '''Quick Calculation Pad''' can provide this result directly and more accurately than the plot.
