Step 1 :First, calculate the total number of people who moved. This is the sum of all the numbers in the table, which is \(12.4 + 3.6 + 0.2 + 19.1 + 5.8 + 0.9 = 42\) million people.
Step 2 :Next, find the number of renters who moved to a different continent. According to the table, this is \(0.9\) million people.
Step 3 :Finally, calculate the probability. This is the ratio of the number of renters who moved to a different continent to the total number of people who moved. So, the probability is \(\frac{0.9}{42} = 0.02143\).
Step 4 :Round this number to the nearest hundredth to get the final answer. The probability, expressed as a decimal rounded to the nearest hundredth, that a randomly selected person from Country X who moved was a renter who moved to a different continent is \(\boxed{0.02}\).
