7. What is the probability you pick a student in theschool and they prefer to use Tik-Tok OR they are aJunior? (Write as a percent rounded to the nearesthundredth)

Probalibity that the student prefer to use tik-tok = 915/1538
= 0.59 or 59.5
Probability that the student is a junior = 287 / 1538 = 0.186 or 18.6
Total = 59.5 + 18.6 = 78.2%
The closest to my answer is letter a.
