All mathematicians love music. Some philosophers love music.
Some philosophers are mathematicians.
The answer is no. Some philosophers could be mathematicians, but there is no way to conclude that any are. Draw three circles that all intersect in the middle. Black out all of circle A, except the part that intersects with circle B, because there are no mathematicians who do not love music. It s possible, therefore, that some philosophers are mathematicians, but you can t tell for sure from the information you ve been given.
