Answer:

The answer to the question is 0.43. Let's explain why.

Step-by-step explanation:

A train arrives at the station at 15-minute intervals starting from 7:00 am which makes the train arrives at;

7:00

7:15

7:30

7:45

8:00

B train arrive at 12-minute intervals starting at 7:07 means B train arrives at;

7:07

7:19

7:31

7:43

7:55

Now, let's review the chances of a passenger arrives at the station any time between 7:00 am and 8:00 am

If the passenger arrives between 7:00 - 7:07 the passenger will get into B train which gives us the $\frac{7}{60}\\$ chance since an hour is 60 minutes and the passenger waited for 7 minutes.
If the passanger arrives between 7:07 - 7:15 passenger will get into A train which gives $\frac{8}{60}$ chance. If we apply this to the time limits it goes by;
Between 7:15 - 7:19 passenger will go to B destination which gives $\frac{4}{60}$ chance
Between 7:19 - 7:30 passenger will go to A destination means $\frac{11}{60}$ chance
Between 7:30 - 7:43 passenger will go to B destination means $\frac{13}{60}$ chance
Between 7:43 - 7:45 passenger will go to A destination which gives $\frac{2}{60}$ chance
Between 7:45 - 7:55 passenger will go to B destination means $\frac{10}{60}$ chance
An lastly between 7:55 - 8:00 passenger will go to A destination which gives us $\frac{5}{60}$ chance
