If a test has 25 questions with 4 possible answers per questions, how many possible answer combinations are there?
100 possible answer questions.
Hope this helps David.(:
I believe there are 4^25 possible combinations.
consider that for each question there are 4 possible answers. It's like figuring the number of license plates where there are 25 letters, each of which may be A-D.
To find the number of possible answer combinations, we need to calculate the total number of possible outcomes for each question and then multiply those outcomes together for all the questions.
In this case, there are 4 possible answers for each of the 25 questions. So, for each question, there are 4 possible outcomes.
To calculate the total number of possible answer combinations, we need to multiply these outcomes together for all the questions. Since there are 25 questions in total, we multiply 4 by itself 25 times (4^25).
Calculating this would result in a very large number, which is beyond the capacity of most calculators and computers to represent accurately. However, it gives you an idea of the vast number of possible answer combinations.
Therefore, the total number of possible answer combinations is 4 to the power of 25, or 4^25.
