Need help re-caging my brain on how to calculate basic probability. Google links sucked.
Scenario in question: Three teammates are taking a test. Each has an 80% chance of passing said test. The whole team passes if two of them pass. What is the % chance of them passing?
I calculated it as follows, but feel like this answer is so covered in mental cobwebs that I need insecticide and and a shower:
4/5 chance of passing (Operator A) x 4/5 (Operator B) x 4/5 (Operator C) = 64/125 = 51.2% chance of all three passing.
4/5 x 4/5 = 16/25 = 64% chance of second two passing if first one failed...but how to calculate for the first dude's chances, and thus the overall problem? Throw in another 1/5 and get 16/125 for failure %, and gives me 87.2% success rate? That passes the sniff test...but I'm shaky on the math.
Thanks for the help in advance. Right answer gets an AMA on my area of expertise :-)1 AnswerMathematics8 years ago
My local bike shop is run by a cadre of very experienced guys. They sized me (using a ton of professional measurements, computers, etc.) for a bike ($1100) that I ended up buying used on Craigslist ($700), so I made sure to go to them when I got it fit to me and bought accessories.
The shop's owner spent 3 hours with me today, during a busy early-spring day where his shop was slammed. He installed aero bars (which I recieved as a gift), installed a seat (purchased from him), and adjusted every damn piece of the bike to my body. We spent 45 minutes on the seats alone, and I tried three different ones on the machine in his shop, and on the roads outside.. He taught me a lot, and really took his time to get it right. I ended up paying him for fitting the bike ($150), a seat ($115), and the shorts ($60).
When I got home, my wife did some comparison shopping for the seat. She found it for $80, shipped. She said I should return it and buy the cheaper on online. I have an ethical problem with doing this, as I received a service from the shop (knowledge, testing, guidance, etc.)
What do you think? What are the ethics of going to a professional store for knowledge on a product, but buying the product elsewhere?2 AnswersSmall Business1 decade ago
Stationed in Camp Lejeune, NC. Current plan is to sell CLNC-area house before deployment, and my wife will live with my parents from this fall until we go to my actual duty station in early '13. 1/2 of our household goods will go to storage, and 1/2 will go with her. Our duty station is in Germany...can't exactly do a DITY move. Adding even more complexity, I'm executing an inter-service transfer in Jun '11, and will be in Benning for ~6 months then Bragg for ~12.
I'm going to swing by the TMO office tomorrow, but if previous experience is any indication, they'll have no clue what to do and no inclination to find out. Any of y'all have experience/info on what my options are?1 AnswerMilitary1 decade ago

Politics is divisive, and military issues are even more so. It's to be expected that people are going to post hateful, angry, inflammatory questions, and even questions that are really just rants in the guise of a question.
But that's what moderators are for, right? That's what "Report Abuse" is for, right? Unfortunately, the system is not working. We just had a board leader (SFC_Ollie) quit because his questionable post was removed, while dozens of flagrant violations go un-noticed every hour.
Who is supposed to be responding to our abuse reports? Why are they not doing so? Is there any way to delegate such authority to members of our community like Mrs. JVB, Perro Del Lava, etc.?3 AnswersYahoo Answers1 decade ago

How to explain that "2 + 2 = 4" is not a matter of opinion? How do you describe that capital-t Truth exists?
Me: "2 + 2 = 4"
Obtuse one: "No it isn't. You can't prove that. You can't prove anything. Nothing is knowable."
