Given year, prob. that snowfall is less than mode of sample

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.

What's the mode? Give us a clue that you have a clue.
