# Math Help - Probability distribution in graph greater than 1: what does that mean?

1. ## Probability distribution in graph greater than 1: what does that mean?

This is a question in my review exercise:

I noticed that at x=1, probability=2. Now what does that actually mean? I cannot concieve a probability greater than one, and I have searched my book's examples in vain. Isn't probability supposed to be always lower than or equal to one? :help:

What gets calculated is [tex]\Pr(a \leq X \leq b)[tex], which is given by $\int_a^b f(x) \, dx$.
