Using the normal distribution calculation tool at http://psych.colorado.edu/~mcclella/java/normal/accurateNormal.html ,
I get 2.28% for the answer.
Enter 100 for the mean and 15 for the std dev. Then enter 130 for start and a very high number for which the probability is negligible (like 200 or more) for the end, and hit the "enter " key.
