K-Company is a distributor that sells high-end outerwear. This coat has a procurement cost of $1,000 and a selling price of $2,000. The company predicts that the demand for this coat will be normally distributed with a mean of 5,000 and a standard deviation of 2,000. After the end of the season, the remaining coats are out of fashion, so the product value has declined and they are going to sell all of remaining coats at $500 per product.1.What is the probability that next season's actual demand will be less than the average of the predicted demand? (Hint: Consider the characteristic of normal distribution)
