Answer:
To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.
The total number of customers who participated in the survey is:
Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers
Total Customers = 88 + 52 + 64
Total Customers = 204
The number of customers who bought printers is 64.
Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:
P(Bought a Printer) = Number of Customers who bought Printers / Total Customers
P(Bought a Printer) = 64 / 204
P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)
So, the probability that the winner of the gift certificate bought a printer from Super Electronics is 0.3137 or approximately 31.37%.
