5. (5 marks) A data packet crosses two different routers before reaching its destination. Assuming the delay introduced by the two routers are exponentially distributed with pdf b₁(x) = μ₁e and b₂(x) = μ₂e-2, respectively (a) Find the pdf of the total delay T required to reach the destination. (b) Compute the expected value of T. (c) Compute the variance of T. To get the marks you need to include all the necessary calculations and explanations in your answer. 6. (5 marks) A data packet is simultaneously broadcasted to two different routers connected to the destination. Assuming the delay introduced by the two routers are exponentially distributed with pdf b₁(x) = μ₁e-¹1 and b₂(x) = μ2e-2, respectively (a) Find the pdf of the delay T of the first packet to reach the destination. (b) Compute the expected value of T. (c) Compute the variance of T. To get the marks you need to include all the necessary calculations and explanations in your answer.
