Hypergeometric distribution

N, x, n, k = 52, 26, 11,7

I HAVE DONE PART I - Calculate the probability of k successes given the defined N, x, and n

P = hypergeom.pmf(k, N, x, n, loc=0) # Code to calculate probability print(P) I NEED HELP WITH PART II - Calculate and code the cumulative probability of k or more successes. Find the probability that at least k cards are black.

the output must be:

0.1628063397551007 - i have got this one

0.24927823677714275 - cannot figure out this one
