1. An integer, seed, to start the random number generator (just as it was done for program 3 - InBetween).

2. An integer, numSharing, specifying how many people must share the same birthday in order to consider a trial successful.

3. An integer, maxPeople, specifying the maximum number of people "in the room".

4. An integer, numTrials, specifying the number of trials to run for each number of people.

psudo code:

create an array representing the days of the year

add birthdays

check to see if any day has more than one birthday in a day.

compute the probability of the having n people born on the same day out of the sample.

one trial:

create the array:

make a new array of 365 ints.

possibly initilize all to 0.

find the number of people. int maxPeople = [the number of people];

randomly add 1 to maxPeople number of days.

see how many birthdays are shared by numSharing

repete the trial numTrials times.
