Hi can some body give me some good examples on the following

f(y) = (60y-6y^2)/1000 <--PDF

for 0 ≤ y ≤ 10

=0 otherwise

for 0≤u≤10

evaluste the following

(1) P(Y<u| Y<4)
(2) P(Y<u| Y>1 and Y<6)

I have not got a clue

Thanks

1)
if u> 4, P(Y<u | Y<4) = 1
if u< 4,


Cheers

Is this true

that for u equal to 10 it would also be one as (y<10 intersection Y < 4)/ = (Y<4/Y<4) =1

I am not sure

Thanks

I made a mistake in the inequality.
Now it is fixed fixed

Cheers

Lower the size of a PDF file and attach different PDF files together as one document?
How can I attach two different PDF files together so that I can save one as only one? And also how can I lower the size of the file?
