This question was started previously, but to help start you want to look for the probability of exactly two kings/ probability of at least one king. Alternatively, you can solve for the # of hands with exactly two kings/ # of hands with at least one king. To solve the denominator, you could either split it up into three cases or do 1 minus the number of ways to get no kings

so (1-(52 choose 48))?
