Final answer:
Tyler displays an amiable behavioral style, known for being cooperative, easy-going, and good at building relationships.
Step-by-step explanation:
Tyler, who is often described by his friends and co-workers as "always ready to jump in" and someone who "goes with the flow," would most likely exhibit an amiable behavioral style. This style is characterized by a cooperative and easy-going nature. Individuals with this behavioral style are often supportive, patient, and good at building relationships. They may not be as goal-oriented as a driver or as outspoken as an expressive, and they are certainly not as detail-oriented and organized as an analytical person might be.
