This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

X~N(500,400) Determine the following
Random Variable X

a) P( X <= 515 )
b) P( X <= 515 | X > 450 ) (note: "|" implies given)
c) P( 20 < X^(1/2) <= 25 ) ( i.e. 20 < "square root of X" < 25 )

please clearly state each step for each part. The attached file states the problem again.
