I can not seem to find this answer for my exam-training that my teaher gave me:
"A company has observed its customers' purchasing patterns and found that:
P(basis) = 0.70 P(service) = 0.60 P(superior ∪ no service) = 0.70
Calculate the probability of a random customer having both "superior" and a "service agreement"."
A fishmonger has observed the following purchasing pattern:
P(fish fillet) = 0.60 P(tartar sauce) = 0.25 P(tartar sauce union fish fillet) = 0.80
Calculate the probability that a random customer buys a fish fillet but does not want tartar sauce.
Thank you so much
