Hi SaraHann,

The question is worded badly, the meaning is not clear.

If something has to happen then it has a probabiliy of 1 r=1

If something has to happent is has a probablility of 0 r=0

All other possiblilities are between these extremes. So this would be 0<r<1

If you have no idea what the probable outcome might be then r could be over the whole range of possibilities

\(0\le r \le 1\)

Does this answer your question?
