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.

Explanation

To find the sample space of the experiment where 3 bulbs are selected and classified as defective (D) or non-defective (N), we can follow these steps:

### Step 1: Define the bulbs
Let’s denote the three bulbs as B1, B2, and B3.

### Step 2: Determine possible classifications
Each bulb can either be defective (D) or non-defective (N). Therefore, for each bulb, there are 2 possible outcomes.
