"Webb2 maj 2015 · It says that the probability that the variate X is between b and a is given (in our example) by ∫ a b 2 x d x where that 2 x is the pdf or X at the point x. This integral turns out to have value ∫ a b 2 x d x = ( b 2 − a 2) And you can see that the probability that 0 ≤ X ≤ 1 is 1 2 − 0 2 = 1 which is comforting -- we knew X had to be in that range.
