A mail-order company classifies its customers by gender (male/female) and by location of residence (urban/suburban). The market research department has determined that 2/3 of their customers are female and that 75 of their customers live in the suburbs. They have also determined that gender and location of residence seem to be independent of one another. Making up the majority of their customers, the females and suburban customers are identified as the focus group for their new ad campaign. If the mail order company will randomly select one of their customers, what is the probability that it will be a suburban customer or a female?
