11. Suppose 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.
Let D denote the event the bulb is defective and N denote the event the bulb is non-defective
The required sample space is:
S = {DDD, DDN, DND, NDD, DNN, NDN, NND, NNN}
