Not at all, the radio can be used in different frequencies at your own will, how do you kill someone with cards?
That would be so odd to see..

I just have one last question for you. If a train left New York at 300 miles per hour, and accelerated speed 15 miles per hour, and traveled a distance of 683 miles, tell me sir: what time would that train reach Chicago?!

Then I still don't understand the problem.

As for suicide by playing card, it would take serious determination but I can think of at least one way (not a subject I'd particularly like to post advice on, even if comically implausible).

Reguardless on overthinking my most simplest of puzzles, of where I spilled it out for you.
There are no locked windows, it is on the main floor, you can easy walk throughout the different areas and find a better joint, like a nice sit down restraunt if you are sort of hungry though, and then established why you where in the room.
Because there is no hard way out, always think about the different outcomes though.

Depends where they are when they eventually die (because eventually they will...).

You are in a room, there are two doors, each with a person (Male or female is irrelevant) standing beside it. One door leads to a horrible death, the other leads to freedom.
Now to the people. One always lies, while the other always tell the truth, but you have no idea which is which. You are allowed to ask exactly one question to exactly one of the people (without knowing if their answer will be the truth or a lie) in order to determine which door will lead to freedom.

What is the question? and what action do you take depending on the answer?

Hadron said:

But the problem for me isn't working out how you could leave the room, it's that being locked in a room for 24 hours isn't a threat to survival in the first place. So the answer to the question "could you survive" is simply "yes", and so there's no puzzle.

First you need to establish some things, like can you easily climb out of the hole, how much water is there and will it flood the hole. If it will flood the hole, maybe you can use it to float out.
Or, if it's just a trickle you can safely ignore it. Maybe wht water has nothing to do with the hole and won't come anywhere near it.
