Since 1900, the magnitude of earthquakes that measure 0.1 or higher on the Richter Scale in CA are distributed normally with a mean of 6.2 and a standard deviation of 0.5, according to data obtained from the I. S. Geological survey. If 4 earthquakes are randomly selected since 1900,find the probability that their mean magnitude is above 6.4 .
