0.25, or 99.25%*

Explanation:

*** If the (%) was an accident, then probabilities are out of 1, and so the #P("A not happening") = 1-P("A happening")=1-0.75=0.25#.

** If it is a percentage then it works like before except probability is out of 100%, and #P("A not happening") = 100%-P("A happening")=100%-0.75%=99.25%#.
