Since the drying times are uniformly distributed between 2 and 8 minutes, the probability of a part drying in less than 6 minutes is the proportion of the total area under the uniform distribution curve to the left of 6. This area is a rectangle with base 6-2=4 and height 1/(8-2)=1/6, so the probability is 4/6 or 2/3. Choice D is the closest option to this value.
