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!
