None of the existing questions is exactly answering my question so I'm posting a new question, but feel free to refer me to some already answered que...

I have taken a probability course last year but we didn't cover that notion. I do know the steps in the discrete case. finding the support of $X + Y$...

I need to show that a subset of a regular language is regular or not. I think it may not be regular but I could not find a counter example. Do you have an...

im sorry if this is a trivial question. As the title stated, how is the degree matrix of a directed graph defined? I looked up wikipedia of degree matrix ...

I want to know What it is and whether there is a difference in the definition when looking at undirected and directed graphs?

I fail to understand the significance or perhaps visualize the use of the multiplicative inverse = $1\over n$ What is the use? And how it can help in prob...

I can plot a bell curve using the formula: $$ Y = \frac{1}{\sqrt{2\pi S^2} } e^{ -\frac{(X-A)^2}{(2S)^2} } $$ where A=mean and S=standard deviation. This ...

This is a really natural question for which I know a stunning solution. So I admit I have a solution, however I would like to see if anybody will come up ...

I am asked to exhibit a construction sequence to show whether the following is a well-formed formula; Let S = {A, B, C, D} $\alpha = ((A\land C) \rightarr...

How to prove that $$ \int_{t_0}^{t_0+T} \sin(m\omega t)\sin(n\omega t)\,\mathrm{d}t$$ will equal to $0$ when $m\ne n$ and $\frac{T}{2}$ when $m=n\ne 0$? B...
