I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

comment Exposition On An Integral Of An Absolute Value Function
Oh, wait, do you perhaps mean the function without the absolute value bars? If that's the case, that's interesting. And that would explain why the graph $|x^2|$ looks the way it does. The portion of the graph of $x^2$ that is underneath the x-axis corresponds to negative outputs; by applying the absolute value function to $x^2$, that "cup" underneath the x-axis is inverted.

But the absolute value function isn't a polynomial...

Is this perhaps too difficult of a problem?

comment Negative Binomial Question Without Exact Values
@HagenvonEitzen $p(F)$ is the probability of failure, and $P(S)$ is the probability of success. I don't think the question wants me to assume the probability of success and failure; I think it asks for a general expression. Yes, the couples continue to breed, until each family has two daughters of their own. The key words are "to have children until."

comment Hypergeometric Distribution Problem With Rocks!
This is how they calculate $V(X)$ in the answer key to my textbook: $V(X)= \frac{5}{19} \cdot 7.5 \cdot (1- \frac{10}{20})$. I just want to know why 5/19 is in the calculation, shouldn't it be 10/19?

For part c), why do you suggest I use expression $(1)$? Why can't I just use the Variance formula for a Hypergeometric distribution: $V(X) = \frac{N-M}{N-1} \cdot E(X) \cdot (1-\frac{M}{N})$?
