Question:
What is the probability a selected restaurant is in a city with a population size between 50,000 and 100,000?

Answer 1

Given That :

Region 1 = North West (NW)	Population 1 = Under 50,000
Region 2 = south West (SW)	Population 2 = 50,000 - 100,000
Region 3 = North East (NE)	Population 3 = Over 100,000
Region 4 = South east (SE) probability of a selected restaurant is in a city with a population size between 50,000 and 100,000 Number of restaurants in city and population size under 50,000 to 100,000 is                                                          = 36 + 36 + 44                                                          = 147 Total number of restaurants = 450 The probability a selected restaurants is in a city with a population size under 50,000 to 100,000 is                                                                            = 147/450                                                                            = 0.3266 The probability a selected restaurants is in a city with a population size under 50,000 to 100,000 is 0.3266.
