#your code goes here
dollar_bill = 2/houses
chance_of_dollar_bill =dollar_bill *100

print(round(chance_of_dollar_bill) )

Answer 1

Ready carefully... you should "round UP".
One of the solutions would be to use ceil() function instead of round().

Fix line with print function
print(math.ceil(...))

Don't forget to import math, in order to use ceil() function.
