The student has a 1/2 probability of getting each question correct. The probability that he passes is the probability that he gets 10 correct+probability that he gets 9 correct+probability that he gets 8 correct:
P(passes)=P(10 right)+P(9 right)+P(8 right)=[(1/2)^10]+[(1/2)^10]*10+[(1/2)^10]*Combinations(10,2)=[(1/2)^10](1+10+45)=56/1024=7/128.

An examination paper with 10 questions consists of 6 questions in algebra-?
If an examination paper has 10 questions and consists of six question in algebra, the other four questions could be geometry, calculus, or trigonometry.
A test consists of 690 true or false questions If the student guesses on each question what is the mean number of correct answers?
Since there are only two options for the answer, on average the student will answer half of the answers correctly.
A student takes a six question multiple choice quiz with 4 choices for each question What is the probability that the student will answer exactly 4 correctly?
P = (6!)/(6-4)!4!=15
What property is -6xy 0-6xy?
If the question was -6xy = 0 - 6xy, then it is the additive identity property of 0. However, due to limitations of the browser used to post questions, most symbols are not visible to us. It is, therefore, difficult for me to be sure what your question was. Hoped I guessed correctly.
What is the differences between the question and questions?
Questions are more than one and question is one its not that difficult
Georgia is taking a 5 question multiple choice quiz in which each question has 4 choices She guesses on all questions What is the probability that she answers exactly 2 of the questions correctly?

What is the probability that someone will answer at least one of the eight questions correctly?
The answer to this question depends on how easy or difficult the eight questions are. If, for example, the questions were based on Godel's incompleteness theorem it is very likely that nobody could answer them - ever.
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} ).
How do you write an answer to a probability question?
Probability questions are not all the same so there is not a single kind of answer: it depends on the nature of the question!
A multiple choice question has has 5 choices What is the probability of guessing it correctly?
There is 1 right answer out of 5 possible answers, so the probability of guessing it correctly is 1/5 or 20% or 0.2.
A test has 2 multiple choice questions each with 5 choices what is the probability of guessing the correct answers to both questions?
You have a 4 percent chance of guessing both answers correctly assuming there is only one correct answer to each question and that you may only answer once per question.

On a true or false quiz with a total of four questions what is the probability of getting all four questions correct given that the answers to the first two questions are correct?
you'd have a 50% chance of getting the 3rd and 4th question correct because you said the first 2 questions are already anwsered correctly :)
Why doesn't Answers.com answer my questions correctly?
because anyone can answer a question.
There are 50 question and you get 90 percent right how many questions were answered correctly?
45 were correctly answered
Students are required to answer 2 True of False questions and 1 multiple choice questions with 4 responses If the answers are all guesses what is the probability of getting all 3 questions correct?
The probability of correct true & false question is 1/2 and the probability correct multiple choice (four answer) question is 1/4. We want the probability of correct, correct, and correct. Therefore the probability all 3 questions correct is 1/2 * 1/2 * 1/4 = 1/16.
