@stitchsplanet Yeah so the 18.5% was a random number. How probability actually works is that if you have a 90% chance of survival 8 times, you multiply .9 by itself 8 times to find the actual chance of survival which is .43 or 43% chance (.9^8=.43).

This is how casinos make money. For example a roulette wheel has 36 numbers + 0 and 00. Betting on red, you would double your money if you are correct, but since 0 and 00 dont count, your odds of success are 18/38 or apx 47.3%. When you bet on red for 2 turns, your odds of success become .473^2 or just 22.43% when fair odds would be 25%.

@tommyfernandezwolff991 I was gonna skip this video because the answer seemed relatively easy, but now I have to watch it.

#feedback let me filter by likes so that I can laugh and then see the best student explanation!

Me: "Phew that was a tough one"

JY: "Alright tough question here"

Me: :D

@DanielNahum sorry B CBT**

@mishashah987 #1 B is not true because the stimulus says "certain region." What this tells us is that we are looking at a small subsection of earth, so it is entirely possible that while plesiosaurs only live in the water, they live in a different region that is filled with water. The major confusion here is likely that you were looking at the stimulus as if it said the entire southern portion of earth. (I made that same mistake at first)

#feedback 5 minutes in you write that a glass of milk -c-> rising blood pressure. This is the opposite of what the conclusion states. This should say lowers BP, unless I'm completely misunderstanding.

@iitwi2003 you're definitely right. I've been getting 90% of these right and this was the first time I watched a video and thought this is just wrong.

I'm confused as to why E cannot be a good answer. The institutions have a purpose, and they can serve another purpose (being serving selfish staff members in their pursuits.) The only reason I can think that E wouldn't be correct is that E says "just as effectively" and we do not know how effective the institutions are at serving each purpose. Someone please chime in. I chose b under time constraints but under blind review, E seems just as appealing to me.

@cxh1120 I'd recommend underlining quickly to keep track of important ideas without fully mapping if you can understand why the correct answer is correct. That's what I do and I'd say it saves a lot of time. I map it during blind review just to really make sure I remember why an answer is correct.

We have 10 minutes for a question like this right... right?

#feedback Please add a warning button so that we don't just click submit after completing one question. If that is too difficult, please add a way for me to mark if I got the question right or wrong when it says skipped.

So for all most statements, should we split them?

I read this as

Large nursery -M> Commercial raspberry grower + guarantee

instead of

Large nursery -M> Commercial raspberry grower

Large nursery -M> guarantee

I just have to say JY was hilarious in this video.

I'm actually so hyped, because I took this test after studying for a few days and couldn't comprehend this question in the slightest. I answered this question before looking at the video, mapped it all out and got the right answer. There is hope!

For reference there were only 2 questions on that test that I couldn't understand so it feels pretty great to get this right. Before watching the foundations, I remember looking at this question for like a full hour.

Would B be correct if "all" were changed to "most" or "many"?

I think the big part a lot of us missed on this question was "arbitrary rule." When the author says that the question is answered by some arbitrary rule, that means that the answer is essentially random. (because if you are answering yes or no due due to something like a head scratch, the answer will be random) Therefore, presuming that there is some order to this randomness will lead someone to make order out of the randomness. (A) The end of the stimulus tells us that the story is coherent and ingenious.The most appealing choice to me or D is incorrect because we are never told if interpreting a dream here does require a coherent narrative. It just tells us that when someone is given random information, they will make an interesting story from it. Moreover as JY stated, we are not interpreting the dream, simply reconstructing it.

Doesn't B point over to objective evaluation of a poem, which points to not PB? As in

discuss aesthetic value -> 2+ readers -> objective eval of poetry -> /Popular Belief

For the opera Problem can someone just confirm that this is the correct interpretation

Trained -M> Recite

/Trained -M> /Recite

But the argument is

Recite -> Trained

This is not a valid conclusion because we cannot take the contrapositive of the second premise: /Trained -M> /Recite to be Recite -M> Trained because there are no contrapositives of most staements.

I'm so glad this Group 1-4 indicators thing is starting to stick because I see myself understanding the sufficient and necessity much faster than before. If you are still struggling, I would suggest skimming the video lessons and redoing the sufficient necessity practice with a fresh mind, and then repeating just the practice the next day again with a fresh mind before continuing.
