## Homework Statement

Find the probability P(x>1)

The function is f(x) = (2/9)(3x -x^2)

## Homework Equations

## The Attempt at a Solution

So,

P(x>1) = ∫ (2/9)(3x-x^2) dx = (2/9)((3x^2/2) - (x^3/3))[1,∞]

When you do the improper integral lim a->∞ [ (2/9)((3(a)^2/2) -((a)^3)/3)] this is just the first part of the evaluation I stopped because it goes to infinity. So If the integral does not converge then I say the event will never happen?
