Answer

Explanation:

Step1: Recall probability formula

Experimental probability $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

Number of favorable outcomes (trains on - time) is 15, total number of outcomes (total trains) is 20.

Step3: Calculate probability

$P(\text{on time})=\frac{15}{20}=\frac{3}{4}$

Answer:

$\frac{3}{4}$
