A multiple choice test has 5 questions each with 5 possible answers. Find the probability of answering all the questions correctly.
A. 1/3,125
B. 1/25
C. 1/625
D. 1/125
I'm on a test, and this is the only one I'm stuck on.
1, b -120
2, a 56
3, c 8-5
4, c -75
5, c 600
The right answer not eny of the others worked I got 0%
The answer is A. 1/3125 5 times 125 5 times is 3125
ITS CONNECTIONS ACADEMY HOMESCHOOLING... geez
To find the probability of answering all the questions correctly, we need to know the number of possible outcomes and the number of favorable outcomes.
For each question, there are 5 possible answers. Since there are 5 questions in total, the total number of possible outcomes is 5^5 = 3125.
To have all the questions answered correctly, there is only one favorable outcome, which is the correct answer for each question.
Therefore, the probability of answering all the questions correctly is 1 favorable outcome out of 3125 possible outcomes.
So, the answer is A. 1/3,125.
Sorry, if you are writing a test, helping you would be cheating.
If you can't answer this easy and straightforward question then you are clearly not prepared to write this test.
(it is really sad that they are allowing electronic devices to be available during a test)
Very sad -- either that the school/teacher is allowing this or that the teacher is clueless enough not to notice.
