An efficiency expert makes periodic checks for weighting errors for a long distance shipping firm. The expert inspects for errors in weighing, in recording weights, and errors in processing the bills of lading. Based on past records, the number of weekly errors for all shipments averages 5.30 with a standard deviation of 1.23, and the frequency histogram approximates a normal distribution. Suppose x is the number of weighing errors that will occur next week. Compute the approximate probability for (x 2).
