A coin is tossed 4 times. Let X be the number of heads in the first two tosses and Z be the number of heads in the last three tosses. Describe the joint distribution of (X,Z) by means of a table.
I know how to find the joint distribution of two independent random variables but I'm not sure how you'd go about with this one as the variables are dependent. Do you have to know how they are dependent first? If so, how would I calculate that?
