What else can I help you with?
In a multiple choice exam there are 5 questions and 4 choices for each question (a b c d). Nancy has not studied for the exam at all and decides to randomly guess the answers. What is the probability?
The probability of Nancy guessing the correct answer for a single question is ( \frac{1}{4} ) since there are 4 choices (a, b, c, d). For 5 questions, assuming each guess is independent, the probability of guessing all questions correctly is ( \left(\frac{1}{4}\right)^5 = \frac{1}{1024} ). Thus, the probability of Nancy answering all questions correctly by random guessing is ( \frac{1}{1024} ).
What is sampling examine well known methods of probability and nonprobability sampling in statistic?
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
Why simple random sampling is the basis for all probability samplings?
It is not: the question is misguided.
What is the probability of getting 75 percent on a four question quiz?
The answer depends on how well you do in the quiz: that is not a random experiment.
What is convergence of probability?
"Convergence in probability" is a technical term in relation to a series of random variables. Not clear whether this was your question though, I suggest providing more context.
What is the probability of answering a true false test question correctly if you make a random guess?
A 50% to 50% chance (half to half).
What is the probability of coming up with correct letter unscrambling through random letter selection of 5 letters?
If I understand the question correctly, the answer is 1/120.
Does anyone else enjoy answering random questions?
Some contributers do enjoy answering random questions.If you'd like to answer a random question, click: Special:RandompageIn addition to your answer your question, this question can be answered by contributers or guests with different opinions.My opinion- I only answer random questions sometimes, but it depends on what I'm in the mood for answering.

How is random chance related to probability?
Probability is the study of events whose outcome is not certain. If the experiment or trial is not random, and the experimenter conducts it in such a way that a certain outcome is obtained, then there is no probability involved: the question is deterministic.
Why simple random sampling is the basis for all probability samplings?
It is not: the question is misguided.
What is the probability that the random variable has a value greater then 3.2?
It depends on the possible range of the random numbers. The question, as stated, does not have enough information to answer. Please restate the question.

What is the probability that the card chosen is a queen?
For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.
Why with random number repeat previous number often?
Given any random digit, there is a 10% probability that the next digit is the same. That is, the probability of the previous number repeating is 10%. Whether this constitutes often (as suggested by the question) or not is a matter of opinion.
