Find x for the following discrete probability distribution: X 4 1/3 3 1/12 2 7/12 1/3 .92 3 2.75 x is undefined because this is not a valid probability distribution. For the following quantities M and the functions f. Set up a table and draw a diagram for the function f. Determine if they are discrete probability distributions. If the problem contains a parameter k, find out what k must be for you to have a discrete probability distribution, and work with this value. If you now have a discrete probability distribution, leave X - f and do the tasks below:. Find ux. Find Var (X) Find OX. Find TX. Find P (X M) X 10 b) M = {1,4} og f(x) = { 0 DP hvis x = 1,2,3,4 ellers
