Suppose a random sample of size n=6 is drawn from the uniform pdf f_Y(y;theta)=(1/theta), 0<=y<=theta for the purpose of using theta (hat) = Y_max to estimate theta. Calculate the probability that theta hat falls within 0.2 of theta given that the parameter's true value is 3.0. A pdf derived in class for theta hat = Y_max is the following: f_Y_max(y) =

(n/theta^n)*y^(n-1).

I'm pretty much completely lost with this one so any help would be great.
