A set of 30 objects has two attributes. The first is size and it can be L (large) or S (small). The second is colour and it can be R (red), Y(yellow) or G (green). The table below shows the number of objects for each case:
What is the joint probabilities p(L, R), p(G, L), and the probabilities p(L), p(G)
My attempt:
p(L, R), p(G, L) = 1/30 * 12/30 = 1/75
p(L), p(G) = 18/30 * 17/30 = 17/50
