Please show all work when solving this question. Please show the step by step work of how this answer was obtained. 

Let \((X, Y)\) be a random vector with the probability density function (pdf) \[ f(x, y) = e^{-(x+y)} \mathbb{1}_{\mathbb{R}_+^2}(x, y) = \begin{cases} e^{-(x+y)}, & (x, y) \in \mathbb{R}_+^2, \\ 0, & \text{otherwise}. \end{cases} \] Find \(P\left\{\frac{X}{Y} \leq t\right\}\). In other words, find the pdf of the random variable \(\frac{X}{Y}\).
