Smith is a weld inspector at a shipyard.  He knows from keeping track of good and substandard welds that for the afternoon shift 5% of all welds done will be substandard.  If Smith checks 300 of the 7500 welds completed that shift, what is the probability that he will find less than 20 substandard welds?
