Foreign-language study. Choose a student in a U. S. public high school at random and ask if he or she is studying a language other than English. Here is the distribution of results: Language Spanish French German All others None Probability 0.30 0.08 0.02 0.03 0.57 Explain why this is a legitimate probability model. What is the probability that a randomly chosen student is studying a language other than English? What is the probability that a randomly chosen student is studying French, German, or Spanish?

Total probability is 1

0.30+0.08+0.02+0.03+0.57 = 1

P(other than English) = 1-0.57 = 0.43

P(F, G or S) = 0.3+0.08+0.02 = 0.40
