Step-by-step explanation:
Total bulbs = 80
Probability of defective bulbs = 45/80 = 9/16
Probability of non warranty bulbs = 32/80 = 4/5

Answer:
2/5
Step-by-step explanation:
The desired ratio is ...
(part-time)/(total) = (part-time)/((part-time) +(full-time)) = 12/(12+18)
= 12/30 = 2/5
The ratio of part-time workers to total workers is 2 : 5.
