I've been stuck on a portion of a stats question and was hoping someone could possibly help!
The manager of a gas station and convenience store tabulates the following facts:
60% of customers purchase gasoline (G)
38% of customers purchase cigarettes (C)
74% of customers purchase gasoline or a drink
18% of customers purchase gasoline and cigarettes
21% of customers purchase gasoline and a drink
15% of customers purchase cigarettes and a drink
3% of customers purchase all three items
What is the probability that a randomly selected customer purchases exactly one of the three items?
Thanks!
