Answer: 0.0114

Explanation:

Since we are given the information that the quality control manager samples 700 LED bulbs and finds out that 8 bulbs have defects in them.

The probability that a bulb selected at random will have a defect will be calculated as follows:

= Number of defected bulbs / Total number of bulbs sampled

= 8/700

= 0.0114

Therefore, the probability is 0.0114.
