Let X and Y denote the number of times the computer freezes in a dav when it runs on the first and the second operating systems, respectively. 0.5 0.05 0.07 0.06 0.12 0.01 0.01 2 0.08 a. Find the marginal pmfs of X and Y b. Are X and Y independent? Justify your...
please show all steps so i can break down a study For the first four problems, we let X and Y be two continuous random variables with joint density f(x,y) given by , 0<x<2,0 < y < (x,y) = 10 otherwise 3. 10pts Which one of the following is the correct formula for the condi- tional density f(x) as well as the correct region on which this density is non-zero? (a) f(x) = 15,0<x< , (b) f(21]) = 4x, }...
Please explain how did you came up with the answer, show work and formulas. I will give you five full stars if you do so.Thank you so much! 7. Your roommate plays video games for anywhere up to two hours on Wednesday nights and for up to one hour on Thursday nights. An expert on "the video game playing habits of roommates" claims that if we let X represent the random variable for how many hours a roommate will play...
