​hundredth, that a randomly selected citizen who moved in 2004 was a person who moved within the same region.

Answer 1

Same-region total = 11.7 + 18.6 = 30.3 million. Total movers = 11.7+2.7+0.4+18.6+4.5+1.0 = 38.9 million. Probability = 30.3/38.9 ≈ 0.779 → 0.78 (rounded to the nearest hundredth).
