What is the probability that the student speaks spanish given that he or she speaks italian?

Based on this info alone, I'd have to say that there is zero probability. 

However, if this student LIVES or HAS LIVED in countries where Spanish is fluent and maybe even one of the official languages, then the probability of this student speaking Spanish is greater. 

Hope this helps!
