In a local restaurant on taco Tuesday, the manager kept track of what the customers ordered. Of the 100 customers, 70 ordered tacos, 50 ordered margaritas, and 30 ordered both tacos and margaritas.
-Find the probability that a customer ordered a margarita, given that s/he ordered a taco.
Homework Answers
P(tacos) = 70/100
P(margaritas) = 50/100
P(tacos and margaritas) = 30/100
Using conditional probability formula,
P(Margaritas | Tacos) = P(tacos and margaritas) / P(tacos)
= (30/100) / ( 70 / 100)
= 30/70
= 3/7 ( OR = 0.4286)

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) =...
