<p>^nvm they beat me to it.</p>

<p>Ya, got that wrong the reason the answer is 1/54 is because:
6,6,6 probability = 1/216
5,6,6 probability = 1/216
6,5,6 probability = 1/216
6,6,5 probability = 1/216</p>

<p>Add them all up 4/216 = 1/54.</p>

<p>Does it make a difference that in the dice problem, they were rolled simultaneously, instead of in an order?</p>

443

<p>Can someone make a consolidated list?</p>

444

<p>Do you guys think the curve on the math section will be harsh, moderate, or forgiving?</p>

445

<p>harsh…i guess. :(((((</p>

446

<p>easier math SAT’s=harsh curve
I don’t think this math SAT was easy…certain questions were hard.</p>

447

<p>I thought this math was actually hard :(</p>

448

<p>No one saw my question up before so im saying it again: </p>

<p>Does it make a difference that in the dice problem, they were rolled simultaneously, instead of in an order?</p>

449

<p>are the tests all the same worldwide? I am reading all these questions and I am pretty sure I didn’t get this dice question you are all talking about :(</p>

450

<p>lets start the consolidated list guys, forget the 1/54 or 1/108 question for now</p>

451

<p>@wagsthedog, i think it doesn’t matter whether they’re rolled separately or together, but the logical thinking would say they were rolled at once. Digression-hate it when you play monopoly with someone who rolls dice one at a time… :)</p>

452

<p>I’m pretty sure the dice question was 1/54…</p>

453

<p>Someone please get silverturtle here to solve the die problem so we can all sleep tonight.</p>

454

<p>1/54 1/54 1/54 1/54 1/54 1/54 1/54 1/54 </p>

455

<p>I put no answer because I was oblivious at the point in time. It’s quite obviously 1/54.</p>

456

<p>what was the question with the answer as 8000 in july? the question… not the answer</p>

<p>i cant remember the question so i cant remember if i got it right or not</p>

457

<p>Please guys, lets stop this dice question discussion. 80% of the thread is about this question. Doesn’t matter now.</p>

458

<p>Since the dice question seemed to trick so many people… possible -1 is 800???</p>

459

<p>Can someone please confirm these:</p>

<p>a/b = 2/3 … I know answer was 3 but was 3 answer choice B?
x^2 > 3/5y^2 … answer choice E?
t,x,y … E. x>y</p>

<p>Yeah, a consolidated list would be nice, but Im too lazy :)</p>
