A company has two plants to manufacture
scooters. Plant I manufactures 80% of scooters
and plant II manufactures 20%. At Plant I, 85
out of 100 scooters are rated standard quality
or better. At Plant II, only 65 out of 100
scooters are rated standard quality or better.
What is probability that the scooter selected at
random came from Plant I, if it is known that
the scooter is of standard quality?
What is the probability that the scoter came
from Plant II, if it is known that the scooter
is of standard quality
