Since we aren't told the number of people involved in the survey, let's make things easier on ourselves and
assign a "nice" value to the number of people involved in the survey.
Let's say there were
100 people in the survey.
When we apply this to our table, we see that
35 people chose TV ads,
22 people chose coupons,
18 people chose store displays, and
15 people chose samples.
35 +
22 +
18 +
15 =
90 So, the table shows the results for
90 consumers
What fraction indicated either coupons or store displays?Among the
90 consumers surveyed,
22 chose coupons, and
18 chose store displays
22 +
18 =
40Fraction =
40/
90 = 4/9
Answer: D
