I think this is it.
=NORMDIST(55,56,4,1)-NORMDIST(52,56,4,…
Just plug it into excel and it will give you your answer.

50 - 50 . for a probability question like this there can only be two possible outcomes . he is or he ain't . so it's 50/ 50 .
think of the lotto . the ODDS are several million to one . the PROBABILITY is 50/50 as there are only two possible outcomes , either you win or you don't .
