Solution, let x be the lambda of king from two drawn, first of all, probability of x is equal to zero, meaning we choose among the two cards that we chose, there's no king card, and this is 48 chose 2 over 52 chose 2, which is equal to 0 .85, and 88 over 2 to 1, probability of x is equal to 1, meaning there's one king to be chosen, there's 4 ways to choose one king, and there's 48 ways to choose a card which is not a king, which is equal to 32 over 2 to 1, and lastly, probability of x is equal to 2, meaning both cards are king, 4 chose 2, which is equal to 1 over 2 to 1.

So in part b, the graph of the distribution is given by the following, here is x, here is p, x is equal to x, 1 over 2 to 1, 32 over 2 to 1, 188 over 2 to 1, here is x is equal to 0, here is x equal to 1, here is x equal to 2...
