Thanks, understood. But I am now having trouble with the following (seems very simple but I cannot conceptualize it): P(at least one H in two flips of a fair coin) Using the P(X) + P(Y) - P(X AND Y), the answer is: = P(H on first flip) + P(H on second flip) - P (H on both first and second flips) =1/...

Good question, I am not sure. Your best bet is calling them to find out, I would assume you can find their number at "mba.com"?

Time? Clock?
Amateur question: Is the remaining test time visible on your screen on test day during all sections of the test?
Thanks!

quadratic/exponential equations
Hi, 1. (x-3)(x+4) ---------- [divided by] = 0 (x+2)(x-3) Since(x-3) cannot possibly equal 0, is it possible to cancel the (x-3) in the numerator and denominator, leaving us with only one solution: x= -4? Or must we leave both expressions in the numerator, giving us two possible solutions: x= -4 or x...

Thanks David, but what about only "or", when there is no "either" before it in the sentence.
"The boys or Mary is/are going to pick you up."
Can it even be a correct sentence without the "either"?

And is a construction such as "having been cut" also incorrect for the same reason?
e.g. "The trenches, having been cut into a 500-acre site, have yielded..."

subject-verb agreement: OR
I learned that for "neither X nor Y", the following verb must agree in number with noun Y. What about two nouns (one plural, one singular) that are connected only by "or"? Does the verb here also agree with the noun nearest to the verb? e.g. "The boys or Mary IS going to pic...

Very interesting, I was completely unaware of that. So the construction 'After + having + past participle' is always incorrect?
Thanks GMATGuru

SC Grockit question - need a grammar expert's advice!
Hi everyone, please refer to the following SC question: http://www.beatthegmat.com/mba/2010/08/16/gmat-verb-tense-practice#comment-12189 I am a little confused about the answer. I had initially chosen answer choice E. I understand now that "which have increased" (in choice C), is more accu...

Thanks Stuart. The fact that 0 is officially considered an even integer wasn't clear to me, hence my confusion. But this definitely cleared it up.
Thanks!

Ok, another question, hopefully I won't correct myself again.. 2x can either be even or odd, doesn't matter, according the statement 1, we only take the values of x for which the compete statement (2x-1) is odd. The only reason of ruling out A would be if x=0 because 2(0)-1=-1 which is odd but that ...
