I want to know the answer to the following question:
What percent of the population has completed non-mandatory upper secondary education?
All the background I'm provided with is that "In Bern, about 50,418 or (39.2%) of the population have completed non-mandatory upper secondary education, and 24,311 or (18.9%) have completed additional higher education (either university or a Fachhochschule).". Is that enough to answer the question?
