By the central limit theorem, it converges to a normal distribution for large degrees of freedom (k). For k > 50 the distribution is sufficiently close to a normal distribution for the difference to be ignored. Specifically, if k tends to infinity, the distribution of tends to a standard normal distribution with ...
mean = k
std dev = √(2k)
That means you can find the zvalue and the corresponding probability ...
z = (x  k) / √(2k)
hope that helps
