Simulation

Simulation is just a simple technique to find upcoming event on the basis of probabiliy.

Lets take an example of toss of a coin:
Probability of Heads is 50% and Tales is 50%.
Lets assign number to them;
01 to 50 is assigned to Heads and 51 to 100 is assigned to Tales.
OK ! lets for our convenience we make it a two digit number,
00 to 49 is assigned to Heads and 50 to 99 is assigned to Tales.
Now, Ask  your friend to tell any two digit number.
Suppose he said '56' then find 56 is assigned to which event??
Yes u r right, 56 is assigned to Tale.
Tales will come, if u toss the coin.
Sameways try some more times and know the upcoming event.
Thats the Simulation technique. enjoy it.
