Find the probability that the 2nd arrival occurs before time $t$. Approach: Let $X_1, X_2$ be i.i.d. Exp($\lambda$). We want $P(X_1 + X_2 \le t)$. Since the sum of $n$ i.i.d. Exponential($\lambda$) variables is a Gamma($n, \lambda$) distribution: $$f_S_2(t) = \frac\lambda^2 t e^-\lambda t1! = \lambda^2 t e^-\lambda t$$ Integrate to find the CDF, or use the memoryless property arguments often used by Ross. We want $P(X_1 + X_2 \le t)$

Ross often includes subtle hints in the problem wording (e.g., "independent," "stationary," or "ergodic"). Ensure the solution you are reading addresses these specific constraints. = \lambda^2 t e^-\lambda t$$ Integrate to find
