No: Predict a fuel efficiency of 25 mpg. In this example, the root node is the decision of the fuel efficiency of the car, and the child nodes are the possible outcomes based on the engine size and weight of the vehicle. Therefore, the two main types of decision trees in machine learning are classification trees and regression trees.
