Doesn't that have two parameters not one? That is why I asked.

I do not think those are doable.

Yes, they are. Recall Normal probability distribution, please.

After this change of variable, I think now the question is easier.

Sorry guys, I made a mistake, the question should be:

A different integration?

I have found a way to integrate this directly, but it is very tricky.

There actually is closed form, but through a different integration.

Actually, the answer is 3
Look at this poster before 2013 Asian Football Championship, the score will be 3:0

#14 Re: Help Me ! » Conditional Statement » 2013-11-28 01:57:45

Let me explain conditional statement via set arguments.

If you know A is true for sure, and you can immediately infer that B is true.
A is true is sufficient condition that B is true.
We can also say that the event A is true is contained in the event B is true.
Like you are in London implies that you are in UK. But the other way around is not necessarily true.

and we can say B is necessary condition for A, for notB is in notA - you are not in UK so you are not in London.

Hope this theory make your logic class a lot easier!

#19 Coder's Corner » Is MikTex a prerequisite to edit any Latex file? » 2012-08-02 20:01:13

I have been searching for good Latex Editor.

However I found that any of them cannot work alone- it has to work with a 1 GB Tex platform called MikTex.

Is there an independent Latex Editor that satisfy basic editing needs?


#20 Re: Help Me ! » Probability of no. » 2012-04-30 19:42:02

choose 3 and choose 6, and choose between 4 and 5, multiplied by number of choosing sequence possibilities

But it is with replacement, so we have to consider 336 and 366

In 1943, US Navy launched an experiment near Philadelphia, in which a battle ship with the crew, became invisible due to a special electro-magnetic field. The ship not only disappeared, but reappeared in a different place and a different day, and the crew has gone mad as well.

This is a REAL time travel case, not a fiction! mad
