Step-by-step explanation

Given the parameters about companies A, B, and C, we can find the probability of the part being defective by multiplying each chance with the percentage of production by each of the companies. This would give;


\begin{gathered} \text{Probabilty(Defective)}=(10)/(100)*(10)/(100)+(50)/(100)*(30)/(100)+(40)/(100)*(50)/(100) \\ =(9)/(25)=0.36 \end{gathered}

Answer: 0.36
