Look at the total possible 14 letter words.
N%5Btot%5D=26%5E14
Look at the total possible 14 letter words without letter repetition,
N=26%2A25%2A24%2A23%2A22%2A21%2A20%2A19%2A18%2A17%2A16%2A15%2A14%2A13
So then,
P=26%5E14%2F%2826%2A25%2A24%2A23%2A22%2A21%2A20%2A19%2A18%2A17%2A16%2A15%2A14%2A13%29=0.013
