Take 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.
