8 In a supermarket, the prices marked on the signs that are placed on the shelf do not always correspond to the current price of the merchandise, since errors may occur when recording price changes. Assume that over time 60% of the price changes are increases and 40% are decreases. Assume also that 93% of the price increases are marked correctly, as are 98% of the reductions. If a price is not marked correctly, what is the probability that the change is a reduction?.
