What is the probability of getting a perfect score in a three-question true or false quiz?

∙ 14y ago
The probability of getting a perfect score in a three-question true or false quiz is 100% if you studied and retained the subject matter and the questions addressed that subject.
If, however, you did not study, and you made pure guesses without any bias towards an answer partially based in your (now rather poor) knowledge, then the probability of getting any one question correct is 50%, so the probability of getting all three questions correct is 50% to the third power, or 12.5%.

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
True or false The' probability that it will rain today is 0.65 and probability that it will rain or snow is 0.55?
False; the "or" is an additive property so the probability of rain or snow muse be greater than or equal to 0.65.
What is the probability of getting a question right simple by guessing?
That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.

What is the probability of answering a 9 question true false test correctly if you randomly guess?
The probability of getting the first answer correct is 1/2 The probability of getting the first two correct is 1/2 * 1/2 = 1/(22) The probability of getting all 9 correct is 1/(29) = 1/512 which is just under 0.2%

True or false The' probability that it will rain today is 0.65 and probability that it will rain or snow is 0.55?
False; the "or" is an additive property so the probability of rain or snow muse be greater than or equal to 0.65.
This is an example of probability?
No, it is not. It is a statement. It is false, but that is not relevant.
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.
