Q and A for the topic: General

Suppose that {N1(t), t ≥ 0} and {N2(t), t ≥ 0} are independent Poisson processes with rates λ1 and λ2. Show that {N1(t) + N2(t), t ≥ 0} is a Poisson process with rate λ1 + λ2. What is the probability that the first event of the combined process comes from {N1(t), t ≥ 0}?

A meter stick is balanced on a stand at the 50 cm mark. A 42 -g mass is placed on one side at the 29 cm mark (i.e., not at 29 cm from the 50, but at the point marked as 29 cm). At what cm mark would you place a 47-g mass so that the system balances? Write your answer in terms of the position in cm on the meter stick (to one place of decimal ) .
