If I mark all answers 'C' in an MCQ (Multiple Choice Questions) exam, what is the probability of passing the exam?
This question touches on the over-all strategy of “testmanship,” which applies a generic answer strategy in addition to whatever knowledge of the subject matter you actually have.This assumes the MCQ you face is relevant to some course of study you are involved with, or some area of knowledge with which you have a working familiarity -but no special expertise.Here’s the over-all approach:Before you start answering, scan the whole test to get an indication of the questioning strategy. Do not assume you must answer the questions in order -unless that’s a test condition.Go ahead and answer the questions where you have a good degree of confidence that you know the answer. Those are your “gimmies.” Let us say that this gives you 25% of the test.Now scan the questions for choices which you know or strongly suspect to be wrong. The more questions with wrong answers, the better, because your actual odds of a correct answer will be between the “possible” answers. If you’ve narrowed it down to two, then your odds on a sheer guess or coin flip are 50–50. Let us suppose that such questions account for half of the test. If so, you pick up another 25% or thereabouts. But don’t guess randomly -make an effort to determine which choice is more probably correct. That give you a slight edge.That leaves 25% of the test which have few or no known wrong answers. In a 4 choice test, your odds on a guess are 25%. Again, use what you DO know to get an edge.Watch out for answers such as “neither A nor D” or “Both C and B.” Hit the BOTH answers first, for any question where you have ruled out at least one answer.Be aware that the wording of some questions may give you a strong clue as to the answer to a subsequent question.Ignore suspicious patterns to answers, such as “all the answers are “B.”In general, apply the above instructions in the order they are given. The idea is to grab the low-hanging fruit first, then work your way up the “tree,” to more difficult material.This website: General knowledge quizzes has many MCQ’s in various areas where you may practice. In a general knowledge test I just took, I scored 9 out of 10 correct, using the strategies above. There were 2 questions which included known wrong answers, improving my odds on a “guess.” There were 2 on which I was completely clueless.Bottom line: some knowledge of subject matter is essential, but knowing how to take the test can be critical.Hope that helps.
Can RAM(random accress memory ) be partitioned? if yes how?
No. RAM does not work that way. It fills up like a bath tub, but once the power goes off the tub or the memory drains.
My computer keeps randomly messing up. The screen goes tan, my start bar moves up & I can't click anything.
Randomly my computer will freak out. It's not like I do something then it does this. My screen will go tan then I will be able to see parts of my backround on my desktop (or like the web page I was on if that is what I had up) then my start bar moves to the top. I can see my mouse moving but I can't click on anything. If I do CTRl + ALT + DELETE it also does nothing. Even when I do it 3 times in a row it won't restart. I have tried right clicking, left clicking and differnet things and my computer won't do ANYTHING. The only way to fix it is to shut down from the front of the tower then restart and everything is fine. Like I said it's random but it is daily. Yesterday I went to make something to eat and came back and it was doing it then just now I was looking up something online and it did it. It's not like it only happens if I'm not doing something or only happens when I am doing stuff. If you have even a little idea please help because I'm out of ideas! Thanks!! :)
My computer keeps randomly making a sound almost like a piano key being pressed? Virus or what?
if you are running windows and your computer is muted, it means that MS-DOS, the base operating system is alerting you of something. it's not a virus, but can be caused by one. if your computer is not muted it's a windows error. the latter happens a lot, especially in windows vista.
A girl randomly stops replying to me while we're texting each other. Does this mean she doesn't like me?
I've gone through that experience before. Yes although there's plenty of fish in the sea and some girls will think you're not the right fit for them. Don't see it as a hit on you personally. Frame it as a challenge. Question why you couldn't keep the conversation going. Most girls like to indulge their own egos so she lost interest in what you had to say after the phase of curiosity for the guy is done and now it's active conversing. They're outlook for being playful is gone, and they're engaged in seeing if you are the right fit. Unfortunately, what a lot of honest guys out there do, is not be able to communicate that honestly through chat. You wind up sounding like every other insensitive guy out there and a girl can make her judgements and move on. So take this as a challenge for yourself to be more empathetic. Ask more emotional questions, her favorite things, tell personal stories so she might open up, avoid asking yes or no questions because there's no hook to keep it going. Learn to show your true intentions in you chats, and she'll get to the point where she starts the convos. There's lots of advice online, I've used Tripp Advice on YouTube to learn a few things. But it's all about being yourself. Find what works for you, good luck! Feel free to add me on facebook.com/nathan8793
Should I randomly follow my crush on Instagram?
Personally, I’m okay with that. I mean maybe you can find out more about him/her through their social media. Even I’m pretty sure social media and real world are pretty much different. It’s still okay to stay connected right? If in the end things didn’t work out between you and your crush, you can unfollow them (I know it sounds too childish).If you want to make it easy, you can ask yourself. What is your intention? Are you just wanna follow just want to stay connected or are you really want to get closer with them. If you want to get closer with them, I suggest you to let’s just talk or speak directly to them, try to figure out how to make a real conversation with them instead of following on social media.Gotta think about it.
What actually does "256 mb of RAM" means?and what is Rom?give me a e.g?
ROM is Read Only memory. It is memory that is programmed, usually by the manufacturer, and can only be READ. There are devices, called Rom Blasters, which you can use to write to the ROM. usually this can only be down once. Once the ROM is blasted, it can't, in most cases but not all, be written to again. RAM is Random Access Memory. It is called so because you can select any address you want to read, so in effect it is random. You do not have to address it in any order. However, for the sack of simplicity, most programs are written in sequential order, so the CPU usually does generate sequential addresses. The 256 is the amount in bytes. A byte is 8 bits with each bit being a 1 or a 0. In this case 256,000,000 bytes or megabytes.
