Answer:
0.6154 or 61.54%
Step-by-step explanation:
Machine B output level= 80%
Machine A output level= 20%
Machine B defective rate = 0.04
Machine A defective rate = 0.10
The proportion of total washers that are defective is:
Therefore, the probability that a randomly selected washer was manufactured by machine B, given that it is defective, is determined by the proportion of defective washers produced by machine B divided by the proportion of total defective washers:
The probability is 0.6154 or 61.54%.
