Probability of getting pregnant

OK, this is a math probability question.
We had a safety meeting this morning where a gentlemen said that he is having his third grandson after his son had a vasectomy and his son's wife had her tubes tied. A quick search says that 1/100 vasectomies will fail and 5/1000 Tubal Ligations will fail.
The question is, how do you combine the probabilites. An explanation would be awesome because I am deemed with coming up with an answer and explanation. Great...
