Uniform distribution simply means that any point is equally likely

along the interval 18-26 deg C. So ANY point (say 20.5) is 12.5%

likely to happen.

All the book is trying to say is that the probability of the

temperature being EXACTLY 20.5 is 0 (the probability of a single point

in a continuous distribution function is zero) but that the

probability of the temperature being "around" 20.5 is 12.5%. That

interval could be say 1/10 of a degree.. so 20.4 -> 20.6.
