1. Let X and Y be independent variables having the exponential
distribution with parameters λ and μ respectively. Find P(X<=Y).

So uh...where did you get the impression that we would do your homework for you?

lolz! thanks for the comment. i enrolled DataCommunication Course but he gave this assignment. I know about the core course but why did he give this?

Theres a high rate of probability that you wont get an answer.

Probability theory has nothing to do with data communication that I know of.

But I think something isn't kosher in the pickle plant here.

axdhakal1 is either so smart, like on an Einstein level, that he can't even figure out how to tie his own shoes, or there is some other game going on that I'm not aware of.

I just can't seem to figure out why a communication class would give out mathematical theory questions. Then we have a person who can't form a sentence properly asking questions on the net, who in addition claims to be a "Masters Student" in his profile.

axdhakal1, how old are you and is English your second language?

axdhakal1 · Post by **axdhakal1** » Sat Sep 08, 2007 2:28 pm

Hi Round eye,
I appreciate your suggestion. Englisk is my second language. I'm not fron USA. I came here to persue my MAsters Degree.
Right now i'm takin Ad Hoc Sensor Network, Routing and Switching and Data Communication.Regarding the relation between Probability and DAta Comunication i can explain that. My professor gave couple of question. This is my first assignment. We can relate the probability with Data Communication. For ex: What is the probability og dropping the packet at node X?
What is the Probability of receiving packet at node X between the given time frame. Let between 0.1 sec to 0,4 second. Depending upon these results we can send acknowledge signals , accept data packets etc.
If you really want to have information regarding my core courses then feel free to ask.
All i need now is to know how to do my assignment?
Thank you

Again, an example of "teachers that teach because they cannot do" (they don't know what goes on in the real workaday world). Questions such as the one posed have no bearing & use in the work world. It's not like a technician will have apply math formulas to determine why a network is having trouble. This math may have some applicability of one is designing & building network equipment from scratch.

Reminds me of that new Naval officer who boards a freighter w/ sliderule in hand calculating how much coal the bin will safely hold & how much coal will be needed to fuel the ship for its journey. Then a lowly deck hand walks by and says, " fill the bin up to that line that's painted there on the side of the coal bin".

A simple high school problem phrased with high sounding words: P = λ / (λ + &#956

x 100 to give a percentage.

thank you for all those suggetion and help. finally i got the answer.Its:
P(X<=Y)=F[sub]x[/sub](Y)=1-e[sup]-λY[/sup]

If you didn't know how to do the assignment why didn't you ask the professor for help, or a classmate?

Part of the learning processes is the learning processes.

did you go through my last quotes. My respected Prof want us to do that. By the way i got the help from my classmates.I think i expect alot from you guys. Expectation kills and sucks.

if you launched a 747 from a conveyer belt, and the belt was moving in reverse, would the plane take off ??

i can't remember exactly how that question goes, well you get the idea right

Brent · Post by **Brent** » Mon Sep 10, 2007 9:38 pm

A plane is standing on a runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?

We do have some math folks on this site. Surprisingly, no one chose to assist you on your homework assignment.

Hey downhill,you mentioned about Mt. everest. Thank you for referencing Mt. everest. i'm proud to say that i from Nepal(Land of Mt. everest and Lord Buddha).
thank you all for having me although i didn tget my required answer.
From this discussion forum all i can expect is to get nonsense answer rather than helping me specially in Maths pro.

This is a general discussion forum. If you wanted help with a math equation you should have gone to a math forum. WHOA! One of those light bulbs just burst over my head!

Stick around and have a good time. You will see math is not something usually discussed as it doesn't have much to do with what goes on around here.

Yes

so the plane is not really moving forward then,

it's like walking on an escalator backwards at the same speed as the escaltor,you will stay in one place

the plane needs wind over and under it moving to lift, does'nt it?

I say no

lol..here we go again. I think the last time this question was asked, the internet imploded, the [H]ardForum db shat on itself (again! haha), and Moses came down to part the land of SpeedGuide. The answer is yes, it takes off since the conveyor can't spin at infinite speed (I thought it was no as well, believe me, but I learned otherwise).

See that's what I would think, the wheels would just spin under the plane, but it wouldn't actually go anywhere, it needs lift.

But, if the plane is going forward, but the belt is going backward, what then? With this I woul say it WOULD fly, because the wheels do not act as thrust for the plane like it does for a car.

but the wheels still need traction for the engines to make it move down the runway to get the lift?

well theoretically if the engine is powerful enough you wouldn't need wheels at all, it'd be a bumpy ride, but as long as you can get the hunk of metal up to speed and create lift it'll fly

the wheels on the plane don't act as thrust

at least it makes sense in my head, i don't know if that is actually right, but kinda sounds logical eh?

no sir, the wheels just roll -- the engines push the plane. think of it this way, the wheels spin normal speed on a normal runway -- the same speed as the plane is moving forward..now, put it on the conveyor and they move at that normal speed + the speed of the conveyor, but the plane moves the same speed..basically, the wheels just spin twice as fast (if the conveyor is matching the plane's speed, somehow). yea, yard's head is gonna implode, glhf, i'm going to sleep
