<p>doubt that</p>
<p>My friend in May got 2 wrong and got a 750
-1 in math would be a 780</p>
<p>it goes:
800, 780, 750, 720*, 700, 690, 680...
* My June Raw Score was a 51 and that was a 720. Seems like that was very hrash as the same in March would've been a 740.</p>
<p>"The probability of obtaining 1 green card by pulling out a card randomly from 40 is 1 out of 4 times.
10 Green Cards/40 Card Total = 1/4
So everytime I draw 4 cards, 1 of them will be green. In order to get 7, I need to draw out 28 cards.
that's how I figured it to be."</p>
<p>I got 29 because everytime you draw a card it changes the possibility...so the first card will 1/40 but then the second one will be 1/39 and so on... or with this rationale it should probably have been 27 as the answer eh?</p>
<p>i had a little notebook with sat practices i've done. officially trashing it!!!! hallaluya</p>
<p>The question said how many to be "sure" to have 37 cards. This means absolutely 100% positive, which has nothing to do with probability. To be sure, you have to be ready for the "worst-case" scenario, which is not getting a green card whenever possible. That would mean the none of the first 30 cards would be green, but the next 7 would have to be. Hence, to be "sure", 37 cards must be drawn.</p>
<p>ienfur speaks the truth. 37 for sure.</p>
<p>as a side note... what do you think 2 wrong will be on this test? brutal 740 or more generous 760?</p>
<p>I've had a bad experience with College Board's math curves. For the PSAT I missed one MC in Math and got a 76 while a friend missed two in Writing and still got an 80.</p>
<p>well PSAT curve is ridiculous... 1 wrong wouldn't be 760.... i think 1 wrong on SAT ranges from 770-790. and 2 will be 740-760.</p>
<p>There was a lot of arguing on the 40 cards question i my school. Many kids claim 28 is the answer while others put 37. When I initially read the question, I immediately picked 37. I think most people made "a question out of a question." Nowhere in the question did it ask for odds or probability. If i remember correctly it asked what "is the least number of cards needed to be drawn for a person to be SURE to have atleast 7 green cards." Many people misinterpereted it as a probability question however not once did it ask for that. It was a great trap answer though. I am positive the answer is 37. Does anyone remember the exact wording of the question?</p>
<p>PS Don't you hate misreading a question? I made such a mistake</p>
<p>dont u hate that they did it on purpose even more?</p>
<p>Im postive that it said sure in the problem. It is NOT a probability question. If one case can refute it then the whole answer is wrong. The only unrefutable one is 37. Do you remember which part of the test it was on? Middle or end of the section?</p>
<p>it was definitely an H question</p>
<p>come on guys...this was a classic problem...rmbr SAT is not HARD just tricky sometimes....so think simple</p>
<p>and well I can assure you it was 37 because as said above... think of the worst case scenario....10+10+10 and then add 7</p>
<p>the answer is 37, it doesn't say anything about probablity.</p>
<p>what was the question whose answer was m/t ? I think it stood for miles/time, but the time unit was hours. the equation was supposed to equal the car's average speed. ex: 100 miles/2 hours= 50 mph. can we confirm?</p>
<p>DiGamma, it was miles and hour, rate = m/h</p>
<p>thanks, I was just unsure when you wrote m/t. what does anyone remember from the math section 6?</p>
<p>holy crap i didnt even look at the other answer choices!!! I think i put put m/h tho eeeee</p>
<p>cmon lol thats like so obvious. m/h = well miles per hour. All the other choices are really random. Like miles x hour.</p>
<p>no i meant between m/t and m/h</p>
<p>i left like 5 or 6 math questions blank. i doubt i got all the ones i completed correct...</p>
<p>hopefully i can pull off at least a 600 :D</p>
