  course
• 110 are enrolled in both a painting and a clay
• 160 are enrolled in a drawing but not a painting
• 60 are enrolled only in a clay course
• 20 are enrolled in all three course areas
• 230 are enrolled in a clay course
• 180 are enrolled in only one of the three areas
• The dean of art is interested to know the answers
  to the questions
• How many students are enrolled in none of these
  three areas?
• How many students are enrolled in at least one of
  the three areas?
• How many of the students are enrolled in at least
  two of the three areas?
