Answer:
92÷100
Step-by-step explanation:
Given
100 bulbs in total among 8 were defective
Hence,100-8=92
As probability=no.of possible outcome (92)
÷total no.of out come (100)
There fore 92÷100 is the probability of non defective bulbs

The formula for finding probablity is -
Number of favourable outcome by no. Of total outcomes
So favourable outcome is 92
And total no. Of outcomes 100
So it becomes 92
—
100
Then do 92/100 in simplest form
