Is it correct for the future tense to also be used to express something probable or supposed. Not only using it to state if something will or will not happen later. I'd found this example:
Pablo no esta aqui. Estará en casa.
Now I guess word for word it means: Pablo is not here. He will be at home. But to suggest an probability; Pablo is not here, he's probably at home. Would the use of the future tense here be incorrect and/or what would be the proper usage. Thank you.
