2) What is the probability a selected restaurant is in the north?

Region Total Population 1 2 3 4 1 38 34 42 42 156 2 39 32 36 40 147 3 40 41 29 37 147 Total 117 107 107 119 450

Explanation / Answer

(1) The probability that a selected restaurant is in a city with a population size under 50,000 = 156/450 = 0.3467

(2) The probability that a selected restaurant is in the north = (100 + 111)/450 = 0.4689
