One institute mandates that for every 100 items scanned through the electronic checkout scanner at a retail store, no more than 2 should have an inaccurate price. A recent study of the accuracy of checkout scanners at the stores of a certain company showed that, of the 70 company stores investigated, 56 violated the institute's scanner accuracy standard. If 1 of the 70 company stores is randomly selected, what is the probability that that store does not violate the institute scanner accuracy standard?
