In a random sampling three items are selected from a lot. Each item is tested and classified as defective (D) or non-defective (N). Write the sample space of this experiment.

Given: There are three sampling item.


To Find: Write the sample space for the given experiment.


Explanation: In the random sampling , three items are selected so it could be


(a) All defective (D)


(b) All non-defective(N)


(c) Combination of both defective and non defective


We have 2 category (N and D) and we have three condition


So, The number of sample is 23 = 8


Sample space associated with this experiment is


S={DDD, NDN, DND, DNN, NDD, DDN, NND, NNN)


Hence, S is the sample space for given experiment
