0.05
0.11
0.40
0.18

Explanation:

Step1: Find total Fairview cyclists

Total Fairview cyclists = 153

Step2: Sum 35+ Fairview cyclists

Sum = 34 (35-46) + 27 (47+) = 61

Step3: Calculate probability

Probability = $\frac{61}{153}$ ≈ 0.3987

Step4: Match to closest option

0.3987 ≈ 0.40

Answer:

0.40
