Let Y be a random variable distributed according to the geometric model with parameter θ, where 0 < θ < 1. In other words, \[ P(Y = y) = \theta(1 - \theta)^{y-1}, \quad \text{for } y = 1, 2, \ldots. \] Suppose that X, given Y = y, is distributed according to the binomial model with parameters y and 1/2.\\ Determine:\\ (a) the probability of the event {X = 1}.\\ (b) the conditional distribution of Y given X = 1.\\ (c) the expectation of X.

Let $Y$ be a random variable distributed according to the Poisson model with parameter $ heta$, $ heta > 0$. Suppose further that $X$, given $Y = y$, has a geometric distribution with parameter $frac{1}{1 + y}$. (Note: a variable $xi$ has a geometric distribution with parameter $p$ if $P(xi = n) = (1 - p)^{n-1}p$, $n = 1, 2, ...$). Determine: (a) the probability of the event $X = 1$; (b) the conditional distribution of $Y$ given $X = 1$; (c) the expectation of $X$.
