You are analyzing a large group of students who are studying different international languages at a major university specializing in linguistics. In going through the data, you observe that:
- 68% study Spanish
- 34% study Portuguese
- 48% study Japanese
- 14% study both Spanish and Portuguese
- 8% do NOT study any of the above three languages: Spanish, Portuguese, Japanese
- 15% study Spanish and French
- 6% study Spanish and Japanese
- 1% study all three languages
- Are the events study Spanish and Portuguese independent?
- Are the events study Spanish and Japanese independent?
- Are the events study Spanish and study Portuguese disjoint?
- If you pick one student at random, what is the probability that that student studies either Spanish or Portuguese?
- What percentage of students do not study Portuguese?
- What percentage of students do not study French?
- What portion of students studies Portuguese but not Spanish?
Note: This may or may not be useful to you in your calculations, but just to help avoid confusion: If we say, for example, that "68% study Spanish", this does not mean that those students study only Spanish. Those students might well also be taking Italian, Mandarin, or any other language.
