Answer:
(a) 0.0833 or 8.33%
(b) 0.40 or 40%
Step-by-step explanation:
Parts line one (n1) = 1,000 parts
Defects line one (d1) = 100 parts
Parts line two (n2) = 2,000 parts
Defects line two (d2) = 150 parts
Total number of parts (n) = 3,000 parts
a. Probability of a randomly selected part being defective:

The probability is 0.0833 or 8.33%
b. Probability of a part being produced by line one, given that it is defective:

The probability is 0.40 or 40%.
Answer:
Step-by-step explanation:
His original gross monthly salary was $1083.34. This means that the total amount that he earned that he earned in the first 6 months would be
6 × 1083.34 = $6500.4
After working satisfactorily for 6 months, Dave received a 7% raise. The amount by which it was raised would be
7/100 × 6500.4 = $455.00
His salary for the next 6 months would be
6500.4 + 455.00 = $6955.40
Dave's gross annual salary would be
6955.40 + 6500.4
= $13455.8
