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. Of smith checks 300 of the 7500 welds completed that shift, what is the probability that he will find less than 25 substandard welds?
I believe the answer is .9960, but I think i missed something. Could you verify the outcome?
