Thank you for the opportunity to help you with your question!

------------------------------------------------------------------

Total number of light bulbs = 110

Number of defective light bulbs = 2% of 110 = 0.02 x 110


Probability that the selected light bulb is defective 

= Number of favorable outcomes / Total number of outcomes

= (0.02 x 110) / 110

= 0.02
