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 between 10 and 20 substandard welds?
