(Look at the attached photo)

Answer Choices:
A) 150/1025 = 6/41 = .146
B) 150/425 = 6/17 = .353
C) 150/260 = 15/26 = .577
D) 260/425 = 52/85 = .612

Answer 1

Total number of 10 grader students = 260 students.

Total number of students who rides the bus and they are of 10th grader = 150 students.

Probability (a student rides the bus given that they are a 10th grader) =$\frac{Total \ number \ of \ students \ rides \ the \ bus \ and \ 10th \ grader}{Total \ number \ of \ 10 \ grader \ students}$

Therefore,

P(E) = $\frac{150}{260}$

Dividing top and bottom by 10, we get

P(E) = 15/26.

In decimals 0.577.

Therrefore, correct option is C) 150/260 = 15/26 = .577.
