Consider again the problem faced by the Beck Company R&D manager (Problem 9). Suppose an experiment can be conducted to shed some light on the technical feasibility of the project. There are three possible outcomes of the experiment:
I1 = prototype lubricant works well at all temperatures
I2 = prototype lubricant works well only at temperatures above 10°F
I3 = prototype lubricant does not work well at any temperature
How would the decision tree be modified to include this information?
