Question 252627
Note: Because we're only concerned with the year 2000, we'll only draw values from the last column.



To find the probability that you select a resident at random that is NOT in the south, simply note that probability that you select an individual that does live in the south is...


P(Resident from the South) = Number of Residents Who Live in the South/Total US Residents = 100.2/281.4 = 0.35608



So the probability of choosing someone from the south is about 0.35608 (about a 35.6% chance).


Since we want everything but residents from the South, just subtract this probability from 1 (ie 100%) to get: 


1-0.35608 = 0.64392



So the probability of selecting a resident that is NOT from the South in the year 2000 is 0.64392 (which is about a 64.4% chance)



Another way to do this is to add up all of the data values in the 2000 column that are NOT the south and divide them by the total 281.4
