Hi there! I need to check the answer of many probability problems. Most of them are quite simple but calculating them by hand is tedious. They are like this: "It's necessary to choose a person for a mission overseas. If you choose him randomly the probability that he speaks a foreign languague is: S=Spanish; F=French; G=German P(S)=0.33; P(F)=0,26; P(G)=0.2; P(S and F)=0.15; P(F and G)=0.05; P(S and G)=0.1 P(S and F and G)=0.02 -What is the probability that he just speaks one foreign language? -What is the probability that he doesn't speak any?" Could be Mathematica useful for solving this kind of problems? Thanks for your help!
