Yay...<br /> With all three values set to 100, the results were interesting, with 50% exceeding and Monte Carlo pi value being 2.5<br /> <br /> Increasing all values to 10000, the Chi square increased to 99% and Monte Carlo pi rose to 3.188, much closer to what we want<br /> <br /> Interestingly, if the values were dropped down to 10, the Chi square returned to 50%, while the Monte Carlo pi dropped to 0...<br /> <br /> ==Task 2==<br /> With the first test the llps was 3 while the expected was 4.22, and on the second it was 7 instead of 6.67.</div>
