Suppose we have two random variables, A and B, where A takes on values a1, a2 and B takes on values b1, b2. Let P(A = a1) = 0.5 and P(B = b1) = 0.5 Suppose a1 and b2 are disjoint (mutually exclusive). What is p(a1, b2) ? What is p(a1, b1) ? What is p (a 1 |b 2 ) ? Suppose instead that A,B are independent. What is p (a1, b2) ? What is p (a1, b1) ? What is p (a 1 |b 2 ) ?

Consider a gas of molecules whose interaction energy $u(r)$ is infinite for $r < r_0$ and negative for $r > r_0$, with some minimum at a value $-u_0$. The plot gives an example: $u(r)$ $r_0$ $-u_0$ $r$ (5) Suppose also that $kT >> u_0$, so that the Boltzmann factor for $r > r_0$ may be expanded according to $e^x \approx 1 + x$. Show that under these conditions the second virial coefficient has the form $B(T) = b - \frac{a}{kT}$, (6) the same as the van der Waals gas! Write what $a$ and $b$ are in terms of $r_0$ and $u(r)$. Argue that $a$ and $b$ are some positive quantities independent of $T$. Note that $a$ and $b$ might involve things like integrals over the potential $u(r)$, but you should be able to argue that $a, b > 0$.
