Hello all, I'm back with another basic probability question:
I know that it involves Bayes theorem somewhere, but I don't understand this question at all!
Note: This isn't an assignment question or anything like that, it's just a textbook question that I need help with.
Thank you
Hey guys,
I don't understand how this question works... I don't understand the answers either. Could someone take me through this step-by-step?

Hello all,
How would I do this question by hand?
I know I integrate from -infinity to +infinity for $f_x,y$, but I have no idea how to do it by hand! My algebra soup is bad, can someone please help me?
P.S I heard some of my friends talking about some 'trick' you can do with the exponential...
Hello all,
I've been stuck on this question for a while and it's annoying the stew out of me!
I know it's a basic definition type of question, but I can't seem to understand it. Can any of you help?
Question:
Let X be a random variable and A be an event such that, conditional on A, X is...
Yeah, that's right. That is the Reduced Row Echelon Form (RREF) for that matrix.
Now in regards to Mx=0. You have to realize that we're dealing with a homogenous equation. Geometrically, this means the lines, planes or hyperplanes represented by the equations in a homogeneous system all pass...
In extension to what has been said, it can also be shown that $a_{ii} = 0$ with the following:
If you have $a_{ii} = -a_{ii}$ for every $i$, you can simply add $a_{ii}$ to the LHS of the equation, meaning you have:
$2a_{ii} = 0$. Solve for $a_{ii}$ and voila, you have shown that the diagonals...
