To solve this question, we analyze the percentages, and doing this, we get that the percentage of total shoppers surveyed intend to purchase only fruits or vegetables (not both) is 12.6%.
Percentages:
63% of the shoppers will make a purchase.
Of those, 80% purchase both fruits and vegetables.
Thus, 100 - 80 = 20% purchase only one.
Percentage of shoppers who purchase only one:
20% of 63%, so:
[tex]p = 0.2*0.63 = 0.126[/tex]
0.126*100% = 12.6%.
Thus, the percentage of total shoppers surveyed intend to purchase only fruits or vegetables (not both) is 12.6%.
