He's talking about the chances of it being rolled five weeks in a row, or a hundred weeks in a row.
If you still think the chance of rolling a six on a regular die in twenty thousand rolls is one in six, then math has escaped you my friend.

Edited by YahyaTV: 11/28/2014 1:30:05 PMMaths does not escape me. I understand what OP is saying and what you are saying. But you do not understand what I am saying. The probability that in any given week that a given piece of armor will drop is 1 in 6. For the same armor to appear 4 times in a row I agree with OPs comment that it is 0.07703% No, the chances of rolling a six on a regular die 20K times in a row are (1/6)^20K i.e. highly unlikely and pretty close to impossible, but the chances of a six rolling on the 20,000th time is 1 in 6 and every other time. A question, what is the chance of Voidfang appearing next week? Is it 1 in 6 or is it (1/6)^5 = 0.01286% If you think the chances of Voidfang appearing next week is 0.01286% then you suffer from Monte Carlo fallacy, because the correct answer is 1 in 6 (assuming every exotic is weighted equally)

It's one in six, and the week after that it will still be one in six, and the week after that, and week after that too, unless they add another item into the mixture. Though if we continue to see the Voidfang Vestments week after week after week, then it's fair to assume that the chances aren't one in six at all. Sorry if I didn't get my point across in my last post.

Exactly. It's mutually exclusive probability. It's exactly the same as the chances of rolling a 6 on a dice 4 times in a row. Anyone who thinks its 1 in 6 still try it. You may be there a while lol 1/1296 ;)

Haha yeah, played many a dice game and can attest to this! EDIT: DAMN YOU YAHTZEE!!!!!

Edited by YahyaTV: 11/28/2014 11:23:31 AMTake a regular die and consider the probabilities: 1st Roll: 1/6 chance to roll a 4 2nd Roll: 1/6 chance to roll a 4 3rd roll: 1/6 chance to roll a 4 4th Roll: 1/6 chance to roll a 4 Chances of rolling a 4 from 6 choices 4 times in a row is (1/6)^4 = 1/1296 But if you notice each roll is always 1 in 6 Now substitute 1st roll / 2nd Roll etc for 1st WEEK and substitute chance to roll a 4, to chance for Voidfang to be on Rotation Each week the chance of a given armor will always be 1 in 6. Whilst I agree the chances of getting the same armor for increasing [b]consecutive weeks[/b] the chances get slimmer every time, but the probability remains the same[b] for a given week[/b] to turn up

You're missing the point completely.

The chances of getting Week 1 Voidfang, Week 2 Heart of Praxic Fire, Week 3 Nemesis Helm, Week 4 Skull of Dire Ahamatra is still 1/1296, explain to me how I am missing the point completely?!

Edited by S2H UK: 11/28/2014 3:40:11 PMThat EXACT order you stated is 1/1296 but we're NOT looking at exact order of items. For 4 DIFFERENT items to come out its 6/6 x 5/6 x 4/6 x 3/6. Which is substantially more chance than hitting the same roll 4 times in a row. Use your head!

Edited by nightwing87: 11/28/2014 4:31:11 PM^This^.. I'm having trouble understanding why this is so hard for people to get! lol.. The fact that Xur has sold voidfang 4 weeks in a row doesn't necessarily disprove that RNG, but the unlikeliness of it supports the idea that what Xur sells may not be completely random. We're just hypothesizing here using statistic. Is it impossible to get voidfang vesements 4 times in a row? No; but is it unlikely? Yes. Edit: Also, the numbers we're using is the assumption that Voidfangs has a 1/6 chance of coming up when it may not have been programmed that way.
