Answer

Explanation:

Step1: Find total number of trains

The total number of trains is the sum of on - time and late trains. So, $279 + 135=414$.

Step2: Calculate experimental probability

The experimental probability $P(\text{on time})$ of the next train being on time is the number of on - time trains divided by the total number of trains. So, $P(\text{on time})=\frac{279}{414}$. Simplifying the fraction $\frac{279}{414}=\frac{31}{46}$ (dividing both numerator and denominator by 9).

Answer:

$\frac{31}{46}$
