   Choose a student in grades 9 - 12 at randomand ask if he or she is studying a language other thanenglish. Here is the distribution of results: Language   Spanish      French      German      Allothers      None Probability      0.26         0.09         0.03            0.03            0.59 (a.) Explain why this is a legitimate probability model. (b.) What is the probability that a randomly chosen student isstudying a language other than English? (c.) What is the probability that a randomly chosenstudent is studying French, German, or Spanish?    Choose a student in grades 9 - 12 at randomand ask if he or she is studying a language other thanenglish.

Explanation / Answer

(a.) this is a legitimate probability model because0.26+0.09+0.03+0.03+0.59 = 1
(b.) the probability that a randomly chosen student isstudying a language other than English = 0.26+0.09+0.03+0.03 =0.41 (c.) the probability that a randomly chosen student isstudying French, German, or Spanish =0.26+0.09+0.03 = 0.38
