Carl is wondering if the train he is riding home from school will leave early, on time, or late. The probabilities are as follows:

train leaves early - - - train leaves on time - - - train leaves late

Probability of each situation is 1/3.

Step-by-step explanation:

There are 3 possibilities

1 - Train will arrive early

2 - Train will arrive on time

3 - Train will arrive late

Formula for Probability of event a is = n (a) / Sum of events

In this case sum of events = 3

So

Probability of early arrival = 1/3

Probability of on time arrival = 1/3

Probability of late arrival = 1/3
