I did it in this way:Because 'decimals ok' wasn't written,I thought the answer would be an integer.Next,because the question was asking for probability,it could only have been 0 or 1.You get three tries!!

I've allowed for decimals now.

Yeah,but still there is no data in the question to evaluate the probability so I would have guessed these two only!!:p

It is imposible to get the question right and wrong so the probability is 0. Only way to get the answer right ;).
