How does one know if

"Hay un incidente ahí; tendrán que llamar a la policía."

should be translated as

1) There is an accident there; they MIGHT have to call the police (probability)

vs

2) There is an accident there, they WILL have to call the police (statement of fact)

Thanks

 I noticed that " me pregunto cuándo van a llegar" was one of the options in this exercise.  Could I have used "van a llegar' instead of "llegaràn" to express probability

Thanks!

In the kwiz, the sentence is: "La matemática y la aritmética no son lo mismo." I understand that we use "lo mismo" when discussing an abstract idea, but in this case, does the phrase have to match the compound subject and verb, los mismos?
