In a box of 12 tape measures, there is one that does not work.
Employees take tape measures as needed and returned after use. You
are the 9th
employee to take a tape measure. Is this a binomial experiment?
| No, the probability of getting the broken pen changes as there is no replacement |
| Yes, with replacement, the probability of getting the one that does not work is the same |
| Yes, you are finding the probability of exactly 9 not being broken |
| No, binomial does not include systematic selection such as “ninth” |
Homework Answers
Solution:
Option (b) is correct.
Yes, with replacement, the probability of getting the one that does not work is the same
The experiment has a fixed number of trials, the probability remains the same in each trial and there are only 2 outcomes(success and failure). So, this is a binomial experiment.
