A survey of 121 college students was taken to determine the musical styles they liked. Of those, 57 students listened to rock, 41 to classical, and 48 to jazz. Also, 26 students listened to rock and jazz, 27 to rock and classical, and 15 to classical and jazz. Finally, 10 students listened to all three musical styles. Construct a Venn diagram and determine the 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) = G
