1996: 48.2
1997: 33.7
1998: 23.5
1999: 43.7
2000: 81.6
2001: 52.8
2002: 23.5
2003: 17.5
2004: 23.5
2005: 62.4

What is the probability that if you pick a year at random, the snowfall will be less than the mode? Assume that you have 100 years of data, which means that you will be using the normal curve method.
