A.

1/5

B.

2/25

C.

4/15

D.

3/25

Correct Answer: 3/25

Explanation

yellow (Color of Cars) = 3 (Number (frequency). white (Color of Cars) = 4 (Number (frequency). Red (Color of Cars) = 8 (Number (frequency). Green (Color of Cars) = 2 (Number (frequency). Blue (Color of Cars) = 6 (Number (frequency). Black (Color of Cars) = 2 (Number (frequency). TOTAL = 25 Thus, the fraction of the total numbers that are yellow is 3/25

yellow (Color of Cars) = 3 (Number (frequency). white (Color of Cars) = 4 (Number (frequency). Red (Color of Cars) = 8 (Number (frequency). Green (Color of Cars) = 2 (Number (frequency).
