Question 4 What is the probability a selected restaurant is in the east or in a city with a population size of 100,000 or less?
Question 5 Asssuming a selected restaurant is not in a city with population size over 100,000, what is the probability the restaurant is in the east?
Question 6A What is the probability a selected restaurant is in the west and in a city with a population size of 100,000 or less?
Question 6B Event A = Selected restaurant is in the west
Event B = Selected restaurant is in a city with a population size of 100,000 or less
Are events A and B mutually exclusive? Prove using your answer to 6A (i.e., cell I67).
Proof:
If mutually exclusive, _______ =__________
Since ________ ______ ______ , these events are______________________

Are events A and B independent? Prove using your answer to 9A (i.e., cell I91).
Proof:
If independent ________, = ______________
Since_______ ____ _____________ , these events are _______________________________
Question 10 What is the probability a selected restaurant is in a city with a population size under 50,000?
Question 11 Given a selected restaurant is not in the southwest, what is the probability the restaurant is in a city with a population size of 50,000 or more?
Explanation / Answer
Ques 4.
The probability that the selected restaurant is in east or in a city with population size of 10000
=P(therestaurant is in east) +P(the restaurant is in a city with population less that, 100000?)
=.5+0=0.5 (intersection part of the two events is 0)
