Suppose you are to throw a dart at a circular dart board with radius 2 inches. let (x, y ) denote the point that you hit on the board (you can assume the board is centered at the origin (0, 0), and that the dart hits somewhere on the board uniformly at random). (a) find the joint pdf of x and y . (b) find the marginal pdfs of x and y . (c) find the conditional pdfs fx|y and fy |x. (d) suppose that the “bulls eye” on the target consists of a small circle centered at the origin with radius 0.25. explain how you would use one of these pdfs to compute the probability of a dart hitting the bulls eye. find this probability an even easier way. (e) what is the probability that x > 1? (f) if you know that x = 1, what is the pdf of y conditioned on this fact? what’s the probability that y > 0.3 conditioned on this fact?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
