My friend and I are both trying this combination, and have both failed 10 times. With a probability of 3/4 (75%) of a regular rainbow each time, our independent probability of each not getting a second DRD in 10 tries is 5.63%, and our combined probability of no DRD for either of is is 0.32%. We are either preternaturally unlucky (possible) or the probability of getting a second DRD is lower than reported (more probable). I'm wondering how that reported 25% value was initially calculated and if anyone else has had similar disappointing results that might indicate an error, or if we just need to go out and buy ourselves some lucky rabbits' feet before continuing.
