I need help with the second question:
A student is taking a multiple choice exam. There are five possible answers for each question.
What is the probability the student will answer the first question correctly? Answer is 1/5
What is the probability that the student will answer the first question incorrectly?
you're kidding, right?
If the chance of a correct answer is 1/5, the chance of a wrong answer is 1 - 1/5.
Got it. 4/5 is the answer. I'm making this probability problems harder than it should be.
Thanks!
To find the probability that the student will answer the first question incorrectly, we need to know the total number of possible answers for the first question and the number of correct answers.
In this case, there are five possible answers for each question, and we know that the student answered the first question correctly with a probability of 1/5. Since there are only five options in total, the probability of the student answering the first question incorrectly is 4/5.
To calculate this probability, you can subtract the probability of the student answering the first question correctly from 1:
Probability of answering the first question incorrectly = 1 - Probability of answering the first question correctly
= 1 - 1/5
= 4/5
Therefore, the probability that the student will answer the first question incorrectly is 4/5.
