comment How much information is in the question “How much information is in this question?”?
I'm trying to research the topic now, but to give me some ground to stand on, if it's just a simple model, what model of computation could be applicable for my question? :)

comment Quantifying “weight” or “control” of a variable to the value of a function?
Thanks. I knew it had something to do with partial derivatives, but this doesn't fully answer my question. Does this mean that the "weight" I'm looking for is, say I'm looking for the weight of $x$ in $x^2 + 1000y^2$, $\frac{partial derivative of x}{(partial derivative of x) + (partial derivative of y)}$ = $\frac{2x}{2x + 3000y^2}$?

comment Find number of divisors upto $10^9$
Do you mean, given any number up to 10^9, you must list down all its divisors?

That's right, they don't need to be. I'm sorry, I should have noted that. Thanks!

comment Exponential Random Variables
I havent brushed up on this, but for (b) and (c), you are supposed to look at their parameters and compare them. For example, (b) is just asking the question, what is the chance that the exponential RV $X$ is going to be greater than $Y$? This is similar to the question, if the RVs refer to time, what is the chance that $X$ takes longer to complete than $Y$? Hint: All you need is division and addition.

Draw a real line on the paper, and an imaginary line in your mind. :)

comment Probabilities: k out of n
Yes. That's the math way of looking at it, but you're right. You could also try thinking about it in more physical terms. Why is the number of ways of choosing a set like {aa,bb} the same as choosing the number of ways of a set with 98 elements? But as the filters are admonishing us, I leave you to think about it. You are right, again, of course. :)

comment Probabilities: k out of n
The reason it peaks at k=50 is because $\frac{100!}{k!(100-k)!}$ when k=1 is the same as when k=99. And it is the same when k=2 and k=98. And so on, up to k=49 and k=51. Generally, ${_n}C_r$ (the combination) is equal when r=k and when r=n-k. Can you see why?

Almost the same. In fact, the binomial distribution is $$\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}$$
