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

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
