Total no. of electric bulbs = 100
No. of defective bulbs = 8
No. of bulbs which are not defective = 100 – 8 = 92
No. of defective bulbs = 8
No. of bulbs which are not defective = 100 – 8 = 92

To find the probability that the bulb drawn is not defective, we need to determine the number of non-defective bulbs and divide it by the total number of bulbs.
Number of non-defective bulbs = Total number of bulbs - Number of defective bulbs
Given that there are 100 bulbs in total and 8 of them are defective, we can calculate the number of non-defective bulbs as follows:
Number of non-defective bulbs = 100 - 8 = 92
Therefore, there are 92 non-defective bulbs in the box.
Now, we can find the probability of drawing a non-defective bulb by dividing the number of non-defective bulbs by the total number of bulbs:
Probability of drawing a non-defective bulb = Number of non-defective bulbs / Total number of bulbs
Probability of drawing a non-defective bulb = 92 / 100
Simplifying the fraction, we get:
Probability of drawing a non-defective bulb = 23 / 25
So, the correct answer is option 'C' which is 23/25.
In summary:
- Number of non-defective bulbs = Total number of bulbs - Number of defective bulbs
- Number of non-defective bulbs = 100 - 8 = 92
- Probability of drawing a non-defective bulb = Number of non-defective bulbs / Total number of bulbs
- Probability of drawing a non-defective bulb = 92 / 100
- Simplifying the fraction, Probability of drawing a non-defective bulb = 23 / 25
Number of non-defective bulbs = Total number of bulbs - Number of defective bulbs
Given that there are 100 bulbs in total and 8 of them are defective, we can calculate the number of non-defective bulbs as follows:
Number of non-defective bulbs = 100 - 8 = 92
Therefore, there are 92 non-defective bulbs in the box.
Now, we can find the probability of drawing a non-defective bulb by dividing the number of non-defective bulbs by the total number of bulbs:
Probability of drawing a non-defective bulb = Number of non-defective bulbs / Total number of bulbs
Probability of drawing a non-defective bulb = 92 / 100
Simplifying the fraction, we get:
Probability of drawing a non-defective bulb = 23 / 25
So, the correct answer is option 'C' which is 23/25.
In summary:
- Number of non-defective bulbs = Total number of bulbs - Number of defective bulbs
- Number of non-defective bulbs = 100 - 8 = 92
- Probability of drawing a non-defective bulb = Number of non-defective bulbs / Total number of bulbs
- Probability of drawing a non-defective bulb = 92 / 100
- Simplifying the fraction, Probability of drawing a non-defective bulb = 23 / 25
