What is the probability in decimals of a student getting at least one answer correct out of ten true or false questions?
0.05 I think is the answer
What are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
The odds of getting 100 percent on a 10 question multiple choice test with 2 possible answers for each question can be calculated using the probability formula. Since there are 2 options for each question, the probability of getting a question right by guessing is 1/2 or 0.5. To calculate the probability of getting all 10 questions correct by guessing, you would multiply the probability of getting each question right (0.5) by itself 10 times, resulting in a probability of (0.5)^10, which is approximately 0.0009765625 or 0.09765625%.
How many questions can you miss to get a 50 percent on a 35 question test?
To get a 50% on the test, you need at least (50/100) * 35 = 17.5 questions correct. If half credit is not possible, you need to get at least 18 questions correct to get a score of at least 50%. A score of 17 will be just shy of 50%.
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.
What is the probability of reading at least 14 of 20 books?
Depends on the probability of reading any.
What is the probability of randomly guessing at least 8 questions correct on a 10 question true-or-false quiz?
It is 0.0547
What is the probability of getting 5 out of 6 True false questions correct?
The answer should depend on how well you know the topic! It also depends on whether you have enough intelligence to make at least some informed guesses.But assuming you do not have that basic intelligence and are still doing the questions by simply guessing, the probability is 0.0938

What are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
The odds of getting 100 percent on a 10 question multiple choice test with 2 possible answers for each question can be calculated using the probability formula. Since there are 2 options for each question, the probability of getting a question right by guessing is 1/2 or 0.5. To calculate the probability of getting all 10 questions correct by guessing, you would multiply the probability of getting each question right (0.5) by itself 10 times, resulting in a probability of (0.5)^10, which is approximately 0.0009765625 or 0.09765625%.

On an eight question true false quiz a student guesses each answer What is the probability that he gets at least One of the answers correct?
The probability of getting at least 1 answer correct = 1 - Probability of getting all answers correct.So in your case it for be P(at least 1 answer correct) = 1 - 1/256where 256 is your sample space, |S| = 2^8.
A student takes a 10 question multiple choice exam and guesses on each question Each question has five choices What is the probability of getting at least 6 correct out of the ten questions?
To calculate the probability of getting at least 6 correct out of 10 questions when guessing on each question, we can use the binomial probability formula. The probability of guessing a question correctly is 1/5, and the probability of guessing incorrectly is 4/5. We need to find the sum of the probabilities of getting 6, 7, 8, 9, or 10 questions correct. This involves calculating the individual probabilities of each scenario using the binomial probability formula and then adding them together.
How many questions can you miss to get a 50 percent on a 35 question test?
To get a 50% on the test, you need at least (50/100) * 35 = 17.5 questions correct. If half credit is not possible, you need to get at least 18 questions correct to get a score of at least 50%. A score of 17 will be just shy of 50%.
If you were to flip a coin 4 times what is the probability of getting heads at least one time?
As the question is "what is the probability of getting at least one head" the correct way to answer this is to ask what is the probability of not getting any heads and then subtract this from 1.The probability of not getting a head in 4 flips = 0.54 (i.e. 0.5 * 0.5 * 0.5 * 0.5) = 1/16.Therefore the probability of getting at least one head is 1 - 1/16 = 15/16.
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.
If a student takes an 8 question true or false quiz and a student guesses each answer then what is the probability that heshe gets at least 1 correct?
The probability of getting at least 1 correct answer is equal to one minus theprobability of answering all incorrect, this would be;P(atleast 1 correct) =1 - P(allincorrect) =1 - (1/2)8 =1 - 0.00390625 ~~ 0.9961 ~ 99.61%
What is least likely in probability?
An impossible event, with probability 0.
