Random numbers in Python

Computer Science Level 3

I run the following Python code: 

1
2
3
4
5
 
import random
x = 0
for i in range(0, 100):
    x += random()
print(x)

What is the probability that a number greater than 45 will be printed?

0.958 0.993 0.55 0.871 None of these 0

Although the random module has been imported, the random method of the module has not. Thus, the code will result in an error.

Crap, I accidentally said "None of these", because I thought you meant that no number will be printed, but I guess in that case 0% is technically correct.
