A:
The table is attached. You need to find the probability, expressed as a decimal rounded to the nearest hundredth, that a randomly selected citizen who moved in 2004 was a person who moved to a different region.
What you need to calculate is the empirical probability: the number of success over the total number of outcomes.
People who moved to a different region = 2.7 + 4.5 = 7.2 millions People who moved in 2004 = 11.6 + 2.7 + 0.4 + 18.7 + 4.5 + 1.0 = 38.9 millions
P = People who moved to a different region / People who moved in 2004 = 7.2 millions / 38.9 millions = 0.18508997
Therefore, the probability that a randomly selected citizen who moved in 2004 was a person who moved to a different region is P = 0.19
