A survey of 105 college students was taken to determine the musical styles they liked. Of those, 40 students listened to rock, 38 to classical, and 50 to jazz. Also, 25 stude listened to rock and jazz, 18 to rock and classical, and 25 to classical and jazz. Finally, 14 students listened to all three musical styles. Construct a Venn diagram and deter cardinality for each region. Use the completed Venn Diagram to answer the following questions. a. How many listened to only rock music? n(only rock) = C
