D because it has decimals
-1. 84 is -8 23/100 as a decimal
Answer:
a
b
Step-by-step explanation:
From the question we are told that
The percentage of ENC made by Alice is P(A) 85% = 0.85
The percentage of ENC made by Byte P(B) 10%=0.10
The percentage of ENC made by Cognizant P(C) = 5%= 0.05
The percentage rate of defect of ENC made by Alice is p = 2.5 % = 0.025
The percentage rate of defect of ENC made by Byte is q = 4.0% = 0.04
The percentage rate of defect of ENC made by Cognizant r = 6% =0.06
Generally the probability that a randomly selected ENC will be made by Alice is
Generally the probability that a randomly selected ENC that was found to be defective will be made by Alice is
Here
is the probability that a randomly selected ENC will be defective and this is mathematically represented as
=>
=>
So
=>
