Questions & Answers about Prawdopodobnie znowu imprezują, muszą mieć dużo czasu wolnego.
How do we know muszą here means "they probably do" rather than "they are required to"?
Through context. Just like the English "must", musieć is used for both strict obligation and epistemic deduction (drawing a logical conclusion). Here, the speaker observes a fact (znowu imprezują) and deduces the only logical explanation: they must have a lot of free time (muszą mieć dużo czasu wolnego).
Why is the phrase czas wolny changed to czasu wolnego in this sentence?
It is in the genitive case because it follows the quantifier dużo (a lot). Whenever you use words that express a vague quantity, like dużo, mało, or trochę, the noun phrase that follows must be in the genitive case to express "a lot of" something.
Could I change the word order to dużo wolnego czasu instead of dużo czasu wolnego?
Yes, dużo wolnego czasu is perfectly natural and actually very common in casual speech. Placing the adjective after the noun (czasu wolnego) treats "free time" as a fixed, classifying category (a specific type of time), whereas putting it before is purely descriptive. Both are correct and interchangeable here.
Is imprezują standard Polish or slang?
