Probability distribution in graph greater than 1: what does that mean?
This is a question in my review exercise:
http://www.mathhelpforum.com/math-he...achmentid=9749
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:
