Thread: [SOLVED] Probability/queue theory (a bit elementary)

Hey, I was wondering if this question looks right to you guys, because I cannot find a value for a other than 0 that will meet the requirements for a pdf. Please show me what I am overlooking. Thanks.

Measurements on a router indicate that the pdf of packet delay (in ms) is approxed by f(t)= , and the avg packet delay is 6ms.

So my qn is, do you guys see a valid value for a that can fulfil the requirements for the pdf? Thanks.

First you have not said that ms. Then any positive value of gives a pdf. So we have the mean is:
