C) Suppose your colleague wants to buy shares of the stock that is the most expensive. Find the probability density function for the price per share that your colleague will have to pay Z. O g(z) = (1 - e-(z-6)) 3 O g(z) = 4e-1(z-6)(1 - e-4(z-6)) O g(z) = e-1(z-6)(1 - e-4(z-6))3 O g(z) = e- 1(z-6)(1 -e-4(z-2)) O g(z) = 4e-(2-6) (1 - e-(z-6))3 SubmitThe opening prices per share of four similar stocks X1, X2, X3, X4 are independent random variables, each with density function *Hi 'f > 6 e 1 33 _ 0 else
