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.
(N/A) Since each bulb can be either defective $(D)$ or non-defective $(N)$,and there are $3$ bulbs,each bulb has $2$ possible outcomes.
Total number of outcomes $= 2^3 = 8$.
The sample space $S$ is the set of all possible outcomes:
$S = \{ DDD, DDN, DND, DNN, NDD, NDN, NND, NNN \}$
Total number of outcomes $= 2^3 = 8$.
The sample space $S$ is the set of all possible outcomes:
$S = \{ DDD, DDN, DND, DNN, NDD, NDN, NND, NNN \}$
