# probability calculation in the side event seems to be broken

So in my opinion something is wrong with the probability calculation in the side event. I've now done 5 runs on Legendary and got the T4 5 times. If this is intentional, I wonder why there must be 7 paths? Anyone else have this problem?

• Well, that does seem improbable. According to the forum post, that path has a 15% chance.
• i run 5 times, t5cc path 5 times in a row. i checked the chance, it's 10%. lol. i always hate RNG rewards
• If you roll a die and get 1 4/5 times is that die broken? No

It's true, I'm not a math genius. But when I read Zola's page, the probability of getting the same path 5 times in a row with 7 paths is 0.14X 0.14 X 0.14 X 0.14 X 0.14 = 0.000005488 That's not true now Exactly, because you would now have to weight the individual paths slightly differently, but even if there was "only" a chance of 0.00054, the probability that something in the game is wrong is much, much higher than it really is .

If that specific rift path is 15%, why did you calculate using 14% (were you just just taking 1/7 for # of rifts ? Each rift has different probability, although that one is actually very close to that 1/7th value)

And even so, doesn’t come out to 5488. And it also has one less 0 between decimal and number. As well as since visually a .01 value already looks bad (it is such a fractional value) but really corresponds to 1% so when displaying a value and implying it as a percent you need to chop another 2 zeroes off of it.

And lastly, assuming the complaint is SAME RIFT (aka, ANY RIFT) 5 times, then really you should take 1 of the multipliers out of the equation. Since once you establish the baseline (first roll of the dice), then it is only the next 4 that would have factored into them being the same as the first.

So odds of getting same rift 5 times in a row for a rift that is of 15% odds is really 0.05% (0.050625%). So for every 2000 players, someone will encounter that.
