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?

Please what x and n and everything else is. And please show all work for points. Please. I do not just want answers. I just need a little help. Thanks
