    import math

    N = int(input()) all_strs = input().split() K = int(input())

    non_a_num = len(list(filter(lambda x: x!= "a", all_strs))) if non_a_num < K: print(1) else: print(1 - (math.factorial(non_a_num)/math.factorial(non_a_num-K))/(math.factorial(N)/math.factorial(N-K)))

    except 2 test cases all pass can any body help me with this code from itertools import combinations as p n = int(input()) s = sorted(input().split()) m = int(input()) a = list(p(s,m)) count = 0 for i in a : if s[1] in i or s[0] in i: count += 1 print(count/len(a))

    from itertools import combinations

# Input
n = int(input())                 
letters = input().split()       
k = int(input())                
combs = list(combinations(letters, k))

countwitha=sum([1 for comb in combs if "a" in comb])
ratio=countwitha/len(combs)
print(f"{ratio:.3f}")
