Probability/chance

nooooo..... i lost my breastplate of valor to a warrior yesterday (in world of warcraft).. the guy not only won my valor , but he got spaulders of valor and 2 brilliant chromatic scales in that same run. In WoW, when a item drops, evry1 has a chance to roll (or pass on it), in which the computer will generate a random number 1 - 100, with the highest number among all winning the item.

So lets try to count the probability of that warrior taking all the loot happening.... figures from allakazam..

Probability of...
Finding a brillant chromatic scale off a Chromatic Whelp --> 0.299
Winning the roll against 15 people --> 0.299/ 15 = 0.001993
Finding another brillant chromatic scale off a Chromatic Whelp --> 0.299
Winning the roll against 15 people again- 0.299/ 15 = 0.001993
These 2 events happening in the same run/time --> 0.001993 * 0.001993 = 0.000003972
Finding Spaulders of valor --> 0.1353
Finding Spaulders of valor and 2 scales AT the same run/time --> 0.000003972 * 0.1353 = 0.0000005374
Finding Breastplate of valor --> 0.0656
Finding Spaulders of valor and 2 scales AT the same run/time and seeing valor drop --> 0.00000003525
Since there are 2 warriors on the raid, he will haf to roll against me, dropping the probability of him getting the valor chestpiece by 0.5
Finding Spaulders of valor and 2 scales AT the same run/time and winning valor BP against me
-----> 0.00000003525 * 0.5 = 0.00000001763

If i convert that probability, it basically means the probability of all that happening at the same time is
1 in 56,721,497 times
Ok i made a mistake im assuming there are only 2 whelps, which is wrong since there are about 20 killed per run, so i will haf to multiply the number i got by (20/2) = 10
which makes 1 in 5,672,150 times

So watch out when people say maaaybeee, they mean theres a chance/probabilty that it may happen, even if its 1 in 5 million , it can still happen. haiz to think i was still joking about about that happening 2 me n it happened..
haiz this is only a mmorg, if u think of how evrything that has happened in ur life n try 2 use probability in it, haha the number will be astronomical... by chance ???
