That depends on how many questions there are, how many choices are listed for each question,
and whether any obviously-stupid answers are included among the choices. If any of those factors
changes, then the probability changes.
One thing we can guarantee, however, even without knowing any of these factors:
If you have studied the subject and know the material, then your probability of getting
correct answers increases dramatically.
The probability of getting both answers correct is one chance in nine (0.1111+). There are three possible answers for each question, so there is a 1/3 chance of getting the correct answer to one question. To get the correct answer for both questions, the chances are 1/3 x 1/3 or 1/9.
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%.
The probability is 7/36
If it is a T/F test; probability correct for each question is 0.5. Since there are 4 questions, raise 0.5 to the 4th power; e.g. (0.5)4. So, probability all correct is 0.0625. If a 4 part multiple choice, P(correct) = .25 so raise .25 to the 4th power, or .003906.
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 :)
The probability will depend on how much you know and the extent of guessing.
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.
Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question. Short Answer: 1/5 times 1/5=1/25
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.
The probability of getting both answers correct is one chance in nine (0.1111+). There are three possible answers for each question, so there is a 1/3 chance of getting the correct answer to one question. To get the correct answer for both questions, the chances are 1/3 x 1/3 or 1/9.
Probability are the odds of something happening but has multiple answers. Such as probability of getting a 5 in a fair dice would be 1 out of 6 because there are 6 numbers on a dice altogether, and ONE chance of getting a 5 from the total of 6. Therefore, the probability of getting a 5 or any number from a dice would be 1/6.
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%.
The answer depends on the number of choices available for each question.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
The probability is 7/36
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%
If it is a T/F test; probability correct for each question is 0.5. Since there are 4 questions, raise 0.5 to the 4th power; e.g. (0.5)4. So, probability all correct is 0.0625. If a 4 part multiple choice, P(correct) = .25 so raise .25 to the 4th power, or .003906.
