Suppose that {X(t) : t ≥ 0} and {Y(t) : t ≥ 0} are two independent homogenous Poisson processes having the same arrival rate λ = 2. Let \(W_n^X\) and \(W_n^Y\) be the waiting times for the n^th arrival for the processes {X(t) : t ≥ 0} and {Y(t) : t ≥ 0}, respectively, n ∈ ℝ. Then which of the following statements are true?
