Answers (1)

Answer:  0.04F

Solution:

The total probability of committing an error = Probability Vinay processes the form × Vinay’s error rate + Probability Sonia processes the form × Sonia’s error rate + Probability Iqbal processes the form × Iqbal’s error rate

\begin{aligned} &=50 \% \times 0.06+20 \% \times 0.04+30 \% \times 0.03 \\ & \end{aligned}

=\frac{5}{10} \times 0.06+\frac{2}{10} \times 0.04+\frac{3}{10} \times 0.03

\begin{aligned} &=0.030+0.008+0.009 \\ & \end{aligned}
