Inter-arrival times problem

  • Thread starter CTK
  • Start date
In summary, the problem involves a Poisson process with rate λ and the task is to find the expected value of the fifth occurrence, given that the first occurrence is known to be 5. The solution is not as straightforward as simply dividing n by λ, as there are other factors to consider.

Summary: inter-arrival times problem

Let {X(t) : t ≥ 0} be a Poisson process with rate λ.

a-) Let Si denote the time of the ith occurrence, i = 1, 2, . . . . Suppose it is known that X(1) = 5. Find ## E(S_{5}) ##.

My attempt: Is the answer simply ## n / \lambda = 5 / \lambda ##? Or is there more to it that I am missing?

Thanks for the help

Why would that be the answer?
