In a laboratory, 3 technicians are analyzing the active ingredient in the product vials. Amir, Betty, and Carlos analyze 0.55, 0
AlladinOne [14]

Answer:

The probability is    P(C | I) =  0.025    

Step-by-step explanation:

From the question we are told that

      The  proportion analyzed by  Amir is  P(A) =  0.55

      The proportion analyzed by  Betty is  P(B)  =  0.30

     The  proportion analyzed by  Carlos is  P(C) =  0.15

     The inaccuracy by  Amir  is   p = 0.6% =  0.006

     The inaccuracy by  Betty  is  b = 0.4% = 0.004

    The inaccuracy by  Carlos  is c = 0.1% =  0.001

Generally the probability of inaccurate analysis is mathematically represented as

     P(I) =  P(A) *  p  +  P(B) *  b  +  P(C) *  c

=>  P(I) =  0.55 * 0.006  +  0.30  *  0.004  +  0.15  *  0.001

=>  P(I) =  0.006

Generally the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos is mathematically represented as

       P(C | I ) =  \frac{P(C) *  c}{P(I)}

=>     P(C | I) =  \frac{   0.15  *  0.001}{ 0.006}

=>     P(C | I) =  0.025
