Question

Suppose 3 bulbs are selected at random from a lot. Each bulb is tested and classified as defective (D) or non — defective(N). Write the sample space of this experiment.

Answer 1

Defective = D

Non-Defective = N

3 bulbs are selected at random from a lot

Sample Space = { DDD, DDN, DND, DNN, NDD, NDN, NND, NNN}

Answer: Sample Space = { DDD, DDN, DND, DNN, NDD, NDN, NND, NNN}

Answer 2

Defective Bulbs = D

Non - Defective Bulbs = N.


Given : Three bulbs are selected randomly -

Answer :

Sample Space = {DDD, DNN, NDD, DND, NNN, NDD, NND, NDN}
