Compute f '(a) algebraically for the given value of a

f(x)=-3/x; a=4 so f ' (x)=_______

f(x)=mx+b; a=19 so f ' (x)=_______



Compute f '(x) algebraically

f(x)=-6x+7 so f ' (x)=______

f(x)=8x-4x^2 so f ' (x)=_______

f(x)=3x^3+x so f ' (x)=______

If there is a group of 35 people out of a total of 118 people, and one of the 118 people is chosen, what is the probability that the chosen person will be part of the group of 35?
I thought that it would be: 35/118 * 1/35 = 0.008613
This probability seems very low to me. And when I try to find the probability that the chosen person IS NOT part of the group of 35, I get a low probability as well (0.008436). I would expect that the two numbers should add to one, which they clearly don't. Any guidance would be greatly appreciated! Thank-you.

2.) y=x sq.rt. of 16-x^2

I started trying to analyze poker strategy by modeling a 2-player, Texas hold 'em no-limit game. I started by identifying all two card starting hands and simulated lots of full games (millions) them to find probabilities of victory for any 2-cards vs. any other 2-cards.

Next I started to map out the ways the game could progress prior to the flop (raises, re-raises, re-re-raises, etc. and with several varying dollar amounts).

Now I am at a point where the complexity of posibilities is become enoormous and I am still dealing with pre-flop strategy (there are addition phases of the game as more cards are played if you don't know how to play hold 'em).

Anyhow, my question is how many people have tried something like this before and gotten lost/ given up along the way? I am starting to feel like I may never be able to fully model the game for 2 players and find an optimal strategy, let alone expand the optimal strategy to 3 to 10 players. Lost cause? Any tips? Thoughts? Thanks!
