The tread lives of the Super Titan radial tires under normal driving conditions are normally distributed with a mean of 30,000 mi and a standard deviation of 7000 mi.

Determine the probability that four tires selected at random still have useful tread lives after 24,750 mi of driving. (Assume that the tread lives of the tires are independent of each other.)
