Machamp

Assuming that every move set is even likely to happen, we can calculate as follows:
P(no KC/CC) = (1 - (5/6)^6)*100% = 66.5%
P(SE all of them) = ((2/6)^6) *100% = 0.13%

I hope this sufficiently answers your question.

RNG bias? It always seems like you get the same move set when you evolve rapidly the same Mon.

Odds for not getting a single Karate Chop / Cross Chop:

(5/6)^6 = 0,334 ~33%

Not a single Cross Chop:

(2/3)^6 = 0,087 ~8,7%

Stone Edge for all:

(1/3)^6 = 0,001 ~0,1%

Getting those exact moves in that exact order (lol):

(1/6)^6 = 0,00002 ~0,002%

So in other words, nothing strange here.

My guess is that there is something more than simple 50/50 on movesets, even if I can't demonstrate it I think that some movesets (at least quick moves in my experience) are more likely to appear than others (Bite on Arcanine, SW on Dragonite...), maybe it's like heads or tails, there are some studies that confirmed that it is not an exact 50/50 game and if the part of the coin that looks up when you throw will have a little more chance of staying up.

But we will probably never know for sure. Anyway I feel sorry for your luck (and I know how you feel, got 3 Dragonites in a row with SW when I want a Dragon Breath one so bad...)

MaChamp has three possible charge moves. So, your odds of not getting cross chop out of 6 tries is (2/3)^6, or ~0.088; not high, but not impossible. I think the karate chop/stone edge one should be usable. I'm using a karate chop/submission. With dodging he can take down snorlaxes that use lick; just karate chop them to death. ZH snorlaxes wear him down too fast, and using submission doesn't shorten the battle by much, except if machamp gets hit with a charge move while using it. The ZH snorlaxes are usually pretty easy to finish off, by whatever's next up in my line up, though. Stone edge would have enough more impact to make a difference.

eh, it happens

While the statistical studies conducted by TSR didn't prove anything, they do show that the hypothesis of the distribution of movesets being uniformly distributed (ie same chance for each moveset), does agree with their data

And having studied statistics myself I can reaffirm that they did good a study in terms of their sampling method, their choice of hypothesis testing, and their mathematical accuracy

Regardless of the actual numbers, I can tell you that it really sucks :-(

Sorry!

I feel your pain. I had 6 bulldoze arcanine in a row, 20+ Snorlax in a row with no body slam. On the other hand I've had good luck on the first try with other movesets that other players have trouble getting. Hopefully you have too. Good luck with your next one.

I understand you. It is so frustrating. I evolved 6 Abras and got 6x confusion for alakazam. 5 of which where C/Shadow Ball and the other one Dazz. No psycho cut no Psyko...

RNG sucks. Been burned by bad movesets on lots of mons. Evolved 9 arcanine and 0 got FF/FB. And out of all 9 evolved only 1 didn't get bite lol. What's the probability of that...

I feel your pain. My first machamp I got kc/cc. I love that moveset. I have now evolved 11 more and have never gotten it again. Starting to think it's a legacy move.
I also love primeape lk/cc. I was building any army for prestiging different level snorlax. The other day on a mass evolve I did 6 of them. 5 in a row were low kick/night slash. What a waste
