Rutherford's experiment consisted of beaming positively charged particles at thin gold foil. According to Rutherford, where in an atom are these particles located?

You are meeting a friend at Fort Myers Airport. According to the Bureau of Transportation Statistics, in 2009 flights into Fort Myers were on time 81.3% of the time, but Southwest had a better record and is on time 84.5% of the time. You cannot remember what airline she is taking but you know that in the past she has flown on Southwest 70% of the time. The plane is late. What is the probability she is on Southwest?
