Answer:

C. 65

Step-by-step explanation:

The table which shows the results of the survey are attached below.

From the table:

  • Total Number of non-social media users = 71
  • Number of non-social media user aged 28 and up = 46

Therefore, the probability that a non-social media user is an older student aged 28 and up

[tex]=\dfrac{\text{ Number of non-social media user aged 28 and up}}{\text{ Total Number of non-social media users}}\\\\=\dfrac{46}{71} \times 100\\\\=64.7\\\\\approx 65\%[/tex]

The probability that a non-social media user is an older student aged 28 and up is 65%.
