Agree with Don.
But what if we want to find probability of on real line?
How we can consider R as sample space?
Is that Sample space should be COUNTABLE and FINITE?
*By the quadratic formula, a is 2.08712 or 47.9128.
The range is 45.8256.
A falls in the range of 1..100 or 99. So the probability is 47.9128/99*
*
*
*Here you are considering Sample space as length of the interval, right? but
i think it should be cardinal({x/x belongs to Q and x belongs to [1,100]}).*
