Solution:
From the given information, we have
P(appetizer) = 0.48
P(dessert) = 0.42
P(appetizer or dessert) = 0.67
We have to find P(appetizer and dessert)
We have
P(appetizer or dessert) = P(appetizer) + P(dessert) - P(appetizer and dessert)
P(appetizer and dessert) = P(appetizer) + P(dessert) - P(appetizer or dessert)
P(appetizer and dessert) = 0.48 + 0.42 - 0.67
P(appetizer and dessert) = 0.23
Answer: 0.23

In a local Japanese restaurant, we found that 35% of all customers order hot meals and that 50% of all customers are members of the American Military Community (AMC). So let P(H) = probability that a customer orders a hot meal = .35 P(C) =P(complement of H) = probability that a customer chooses a cold meal = ? P(M) = probability that a customer is a member of the AMC = .50 P(O)=P(complement of M) =...
