A KMU fish farm classifies customers as heavy, medium, or light purchasers, and separate discounts are prepared for each of these groups. Overall, \( 20 \% \) of the members are heavy purchasers, \( 30 \% \) medium, and \( 50 \% \) light. A member is not classified into a group until 18 months after starting to purchase from the fish farm, but a test is made of feasibility of using the first 3 months' purchases to classify the customers. The following percentages are obtained from existing records of customers classified as heavy, medium, or light purchasers. \begin{tabular}{|l|l|l|l|} \hline \multirow{2}{*}{\begin{tabular}{l} First 3 months \\ Purchase \end{tabular}} & \multicolumn{3}{|c|}{ Group (\%) } \\ \hline & Heavy & \multicolumn{1}{|c|}{ Medium } & \multicolumn{1}{|c|}{ Light } \\ \hline 0 & 5 & 15 & 60 \\ \hline 1 & 10 & 30 & 20 \\ \hline 2 & 30 & 40 & 15 \\ \hline \( 3+ \) & 55 & 15 & 5 \\ \hline \end{tabular} II a custormer purchases no fish in the first 3 months, what is the probability that the customer is a light purchaser?
