The more who join, the more shamelessness for us all. This should be fun for everyone and we are doing something good.<br /><br />God bless.Mrsupolehttps://www.blogger.com/profile/01563854387767106508noreply@blogger.comtag:blogger.com,1999:blog-33731975.post-27021914246389512132009-06-16T18:15:53.467-04:002009-06-16T18:15:53.467-04:00I worked it out before I checked the responses so ...I worked it out before I checked the responses so I wouldn't cheat. I did it as a quick chart 1/1, 1/2 and so on to the first line, 6/1, 6/2 in the last. Then it was wasy to see that 1 first would yiled no correct answers, 2 first 1, and so on to 5 if 6 is first, for a total of 15 out the of the 36 possible spin combos.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-33731975.post-54272692974975261072009-06-14T13:35:19.934-04:002009-06-14T13:35:19.934-04:00I'm sorry but that test is just wrong -- there...I'm sorry but that test is just wrong -- there needs to be an F.

The answer is really quite simple:<br /><br />15/36 consists of<br /><br />2/1<br />3/1<br />3/2<br />4/1<br />4/2<br />4/3<br />5/1<br />5/2<br />5/3<br />5/4<br />6/1<br />6/2<br />6/3<br />6/4<br />6/5<br /><br />Thus, there are a total of 15 our of the 36 possibilities that satisfy the requirement that the ratio be greater than 1.<br /><br />I often find the SAT math problems are most easily solved quickly by a common sense approach instead of an equation.Barbarahttps://www.blogger.com/profile/11724807799695867204noreply@blogger.comtag:blogger.com,1999:blog-33731975.post-9839631080896108562009-06-10T21:02:22.010-04:002009-06-10T21:02:22.010-04:00It's really easy:

That may be what the SAT expects you to do, since it is a timed test. But I am a do-er, so here is how I solved it.<br /><br />1. I opened up an Excel spreadsheet, and in the cells of the first column I entered all the values of all the possible combinations -- 1/1, 1/2, 1/3, ... 4/6, 5/6 6/6. That told me there were 36 possible combinations. (I should have been able to know that before I started, but my math education was woefully weak in the area of permutations.)<br /><br />2. The problem asks for the probability of any given pair of spins yielding a number greater than one. So I sorted the column of numbers into increasing order; the lowest is .17 (1/6) and the largest is 6 (6/6).<br /><br />3. The first 21 numbers in the sorted column are 1 or less; the last 15 are greater than 1. Therefore, the answer is 15/36, or A.<br /><br />4. I heaved a huge sigh of relief because when I figure out something like this, it is a total crap shoot as to whether I get the right answer the first time.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-33731975.post-42033442295725332692009-06-03T22:29:22.394-04:002009-06-03T22:29:22.394-04:00GAH!
