Question 44522
Pe(B) = 0.5 
Pe(D) = 1 
Pe(F) = 0.9 
I have to match them to the following 
This event occurred every time
There was a bug in the program
This event occurred often, but not every time
This event never occurred
This event occurred half the time.
-----------------------------------------------
Pe(B)=0.5 This event occurred half the time.
Pe(D)=1   This event occurred every time.
Pe(F)=0.9 This even occurred often, but not every time.
