In this exercise, I’m getting 0.0 for the probabilities of both the no_emails and b_test_emails, yet the answers are showing as correct. Is this a bug or is this in fact the correct answer? Code as follows:

import numpy as np

emails = np.random.binomial(500, 0.05, size=10000)
no_emails = np.mean(emails == 0)

b_test_emails = np.mean(emails == 0.08)

print no_emails
print b_test_emails
