Hi Powerscore,

Please tell me what is wrong with the following argument;

The only possible results are X, Y, or Z.
X is unlikely and Y is impossible.
Therefore, Z is going to be the result.

If there are only three possible results and you eliminate two, shouldn't the only one left to be most likely the result?

Thanks in advance.

Hi H,

The problem with the argument is in the force of your conclusion. You've concluded that Z is going to happen for sure, and that's too strong. The appropriate conclusion is that Z is likely to happen, and that's because there's still a chance X could occur. As long as X could occur, you can't say for sure Z is going to happen.
