PLEASE any help I will appreciate..

here is python code..

#!/usr/bin/env python
import random # Get a random number generator.
NTRIALS = 10000 # Enough trials to get an reasonably accurate answer.
NPEOPLE = 30 # How many people in the group?
matches = 0 # Keep track of how many trials have matching birthdays.
for trial in range(NTRIALS): # Do a bunch of trials...
taken = {} # A place to keep track of which birthdays
# are already taken on this trial.
for person in range(NPEOPLE): # Put the people’s birthdays down, one at a time...
day = random.randint(0, 365) # On a randomly chosen day.
if day in taken:
matches += 1 # A match!
break # No need to look for more than one.
taken[day] = 1 # Mark the day as taken.

Hi,
If you do not have python on your machine, you are not riunning the codse currently, so why do you want to port it ?

You can use the Random Number Generator (RNG)product:

Your python code comes from:
kochanski.org/gpk/./teaching/0501Oxford/MonteCarlo.pdf

Could you also please revisit your previous threads and tidy them up (award points and close), for example:

Hi,

I remember discussing "the birthday" problem in one of my CS classes...

#!/usr/bin/sh

typeset -i NTRIALS=10000
typeset -i NPEOPLE=30
set -A TAKEN
typeset -i MATCHES=0
typeset -i CURTRIAL=0
typeset -i DAY

while [[ ${CURTRIAL} -lt ${NTRIALS} ]]
do
DAY=$(( ${RANDOM}%365 ))
if [[ ${TAKEN[${DAY}]:--1} -gt 0 ]]
then
MATCHES=$(( ${MATCHES}+1 ))
TAKEN[${DAY}]=$(( ${TAKEN[${DAY}]}+1 ))
else
TAKEN[${DAY}]=1
fi
#echo "Trial: ${CURTRIAL} Day: ${DAY} Matches: ${MATCHES}"
CURTRIAL=$(( ${CURTRIAL}+1 ))
done
echo "Matches: ${MATCHES}"
exit 0
