This is probably a very simple problem

Y is distributed by the chi-squared distribution with 5 degrees of freedom. Calculate the probability that Y>9.24.

I know this means that Y is the sum of 5 squared standard normal distributed variables. I can calculate the probability for any individual standard normal variable. Not sure what to do
