A hair stylist placed an ad on the home page of the online community shopper website. Daily site visit demographics indicate the following age categories of visitors:

Age CategoryAge RangePercent of Site Visits

AYounger than age 18 10

BAges 18 to 24 13

CAges 25 to 36 15

DAges 37 to 51 27

EAges 52 to 63 21

FAge 64 and older 14

What is the probability that either a person in age category D or a person in age category E will view the advertisement, assuming there is no relationship between the site visitors?
