Problem 1. Suppose that 3 marbles are chosen without replacement from an urn containing 5 white and 8 blue marbles. Define $X_i = \begin{cases} 1 & \text{if } i\text{th marble chosen is white,} \\ 0 & \text{otherwise.} \end{cases}$ Find the joint probability mass functions of (i) $X_1$ and $X_2$, (ii) $X_1$, $X_2$, and $X_3$.
