Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of
, that is, coming from A.
0.05 of
, that is, coming from B. So

Complimentary = 90 degrees
Supplementary = 180 degrees
Compliment of 51:
90 - 51 = 39 degrees
Supplement of 39:
180 - 39 = 141 degrees
The supplement of the compliment of a 51 degree angle is 141 degrees.
