 # I have a problem with probability calculator and can't find a solution

Hi everyone, I have the probability near 0.45 and do not know where is a mistake

Here is my code

``````import copy
import random

class Hat:
def __init__(self, **balls):
self.contents = []
for k in balls.keys():
for v in range(0,balls.get(k)):
self.contents.append(str(k))

def draw(self, amount):
pulled_balls = []
if amount > len(self.contents):
self.contents.extend(pulled_balls)
else:
for n in range(0, amount):
contentslenght = len(self.contents)
randomnumber = random.randint(0, contentslenght - 1)
pulled_balls.append(self.contents[randomnumber])
self.contents.remove(self.contents[randomnumber])
return pulled_balls

def experiment(hat, expected_balls, num_balls_drawn, num_experiments):

m = 0
n = 0
for r in range(num_experiments):
expected = list()
balls = copy.deepcopy(hat)
allballs = balls.draw(num_balls_drawn)
for v,k in expected_balls.items():
expected += k * [v]

if(all(item in allballs for item in expected)):
m += 1
n += 1

print(expected)
print(allballs)
print(m)
probability = m / n
return probability
``````

Error message :

`all(item in ["green", "blue"] for item in ["green", "green"])` is True.
You can’t compare the two lists with that line.
