When a firefighter arrives at the scene of a fire, they must assess the type of fire to determine the correct way to extinguish the fire and reduce the hazard.  Through training and experience, firefighters correctly identify the type of fire 98% of the time.  If they diagnose the fire correctly, they are 99% likely to choose an effective fire suppression approach.  However, if they diagnose the fire incorrectly, there is only a 25% chance that they will choose an effective approach.  Use this information to develop a THERP model.  Calculate the probability that the firefighter uses an effective approach to fight the fire.
