4. Using the given information, fill out a Venn Diagram and use it to answer the questions. Once the Diagram is filled out, you don't need to show any work to answer the questions. Out of 130 students surveyed, 38 have been to South America, 56 have been to Europe, and 64 have been to Asia. 17 have been to South America and Europe, 14 have been to South America and Asia, and 26 have been to Europe and Asia. 11 of those surveyed said they have been to all three. Question 1: How many students surveyed have not been to any of these three? E S Question 2: How many students surveyed have been to South America and Asia but not Europe, or have been to at most Europe only? (This is one single question, so your answer should be one number). A
