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

Is this part of my comment true as well: "Also, each of the three families will have the same number of boys, because the probability of each family having a boy is the same?"

Yes, thank you!

Why wouldn't it just be $Y=X_1+X_2+X_3$, where $X_1$ represents the number of boys from the first family, $X_2$ represents the number of boys in the second family, and so on. Also, each of the three families will have the same number of boys, because the probability of each family having a boy is the same?

So, in short, my analysis is correct?

comment Negative Binomial Question Without Exact Values
Wait, are you defining a random variable for each family? Also, I just noticed that you have $k-th$ failure, and $r-th$ failure, what's the difference?

Also, just to be clear, the way you are solving this is by considering a girl's birth a failure, and a boys birth a success? And our random variable will count the number of successes, until the $r-th$ failure?

I understand what you are doing for the most part, I just don't understand why it's necessary to use so many different types of random variables. Aren't $G_i$ and $X_i$ the same?

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.
