Final answer:
Without specific information on Bettye Washington, one cannot determine her degrees; however, a psychology professor generally needs a bachelor's, master's, and a PhD in psychology.
Step-by-step explanation:
The inquiry about Bettye Washington's degrees does not provide enough specific information about her to determine her educational background. Typically, to become a psychology professor at a 4-year college, one would need advanced degrees in psychology. The levels of education can include a bachelor's degree (either a Bachelor of Science or a Bachelor of Arts), followed by a master's degree, and most commonly, a PhD in psychology is required for a professorship.
Overall, educational attainment is important for various positions in society. For instance, those in lower-middle-class professions often hold bachelor's degrees from four-year colleges or associate's degrees from two-year community or technical colleges. Meanwhile, professions in fields such as business, management, law, or medicine generally require higher educational levels, including master's and doctorate degrees.
