A true-false test has 12 questions. What is the probability of guessing the correct answers to all of the questions?
A. Start Fraction 1 over 4096 End Fraction
B. Start Fraction 1 over 144 End Fraction
C. Start Fraction 1 over 24 End Fraction
D. start fraction 1 over 14 end fraction
The probability of guessing the correct answer to one question is 1/2 (since it's a true-false question). Therefore, the probability of guessing the correct answer to all 12 questions is (1/2)^12, which simplifies to 1/4096. Therefore, the answer is A. Start fraction 1 over 4096 end fraction.
I'm not sure if you're looking for a serious answer, or if you're just clowning around like me. But if we assume each question has two options (true or false) and you're just guessing randomly, then the probability of guessing the correct answer for each question is 1/2.
To find the probability of guessing all 12 questions correctly, we multiply the probabilities together: (1/2) * (1/2) * (1/2) * ... * (1/2) (12 times).
So, the probability is (1/2)^12, which simplifies to 1/4096.
So, the correct answer is A. Start Fraction 1 over 4096 End Fraction. But hey, don't worry! If you're feeling lucky like a clown, go ahead and give it a shot!
To calculate the probability of guessing the correct answers to all 12 questions on a true-false test, we need to determine the probability of guessing a single question correctly and then raise that probability to the power of the number of questions.
Since each question has two possible answers (true or false), the probability of guessing a single question correctly is 1/2 or 0.5.
Now, to calculate the probability of guessing all 12 questions correctly, we need to raise this probability to the power of 12.
P(correct answer on a single question) = 1/2 = 0.5
P(correct answers on all 12 questions) = (P(correct answer on a single question))^12 = (0.5)^12
Calculating this, we get:
P(correct answers on all 12 questions) = 1/4096
Therefore, the correct answer is A. Start Fraction 1 over 4096 End Fraction.
To find the probability of guessing all the correct answers on a true-false test with 12 questions, we need to calculate the probability of guessing each question correctly and then multiply those probabilities together.
Since each question has two options (true or false), the probability of guessing one question correctly is 1/2. Therefore, the probability of guessing all 12 questions correctly is (1/2)^12, which simplifies to 1/4096.
So, the correct answer is A. The probability of guessing all the correct answers is 1/4096.
