Create probability distribution function from given probalbilty

I would like to have a program that calls a random funtcion which gives either 0,1,2 as result for a defined number of times and counts the result for each run. With using the random.randrange(0,3) I get an equal distribution.

How can I get a distribution with the following probability.

0: 0.4633

1: 0.3147

2: 0.2218

These numbers are variables that I calculated in a different function and they change after I run the function again.

import random

zeros = 0
ones = 0
twos = 0

for i in range(10000):
    a = random.randrange(0,3)

    if a == 0:
        zeros = zeros + 1
    if a == 1:
        ones = ones + 1
    if a == 2:
        twos  = twos + 1


print "zeros = ", zeros
print "ones = ", ones
print "twos = ", twos

zeros = 3345

ones = 3326

twos = 3329

Wanted:

zeros = 4633

ones = 3147

twos = 2218

Thank you in advance :)
