Alright math majors…what are the odds of only one 7-star for 5700 units?

Someone has run some numbers and come up with an outlay of 5700 units being necessary for 100 points and a guaranteed 7-star.
Here’s my question: if you do that, what are the odds that you strike out on your 50 crystals for any other 7-star?
Iirc, last year there were two types of crystals with two different probabilities.

if we take the nexus also into count, its 2.5% total. so tht wud be 1/40 crystals.
If we don't take the nexus into count? 50 crystals is actually how many it wud take for a 7 star.
But this is obv RNG, so the real chance varies a lot, but on average, u shud get atleast 1 other 7 star from the crystals.
That’s the valiant crystal. I’m not certain what the paragon crystal is, think it’s half the 7* drop rate similar to the regular paragon and valiant crystals so I’ll assume that.
From the delta mission track last year, there were 14 paragon crystals and it’s been stated this track is identical (not sure where the info going around that there’s 19 crystals has come from). So this is your breakdown:
Paragon crystals: 14 at 1.5% chance
Valiant crystals: 36 at 3% chance
Possibility of no 7* is: (0.985^14) * (0.970^36) =0.27
So, you have a 27% chance of striking out. 73% chance of pulling at least one 7* champ. 50:50 whether that’s a HoF champ or a random 7* from the basic pool.
Now you add a Nexus Crystal into the mix? Your odds goes down. See, in a standard crystal you got a 2% chance. But with the Nexus? That jumps to a 3.5% chance—if you believe in miracles.
But you? You got a 97.5% chance of pulling disappointment, 'cause the system’s rigged agaist you! And the devs? THEY KNOW they ain’t giving us no 7-stars, and they’re not even gonna try!
So when you take your 2% chance, minus your p2w luck of 85%, you got a NEGATIVE 83% chance of success. But me? Idc about rng but then I add my Nexus bonus, multiply by chances of uninstalling the game, and I got a 141 2/3% chance of pulling that 7* Tigra.
Got my 2nd, 3rd, and 4th choices. Sadly no Fury yet, but pretty happy with FAM. Probably should be more happy with Tigra but I’ll admit I’m not super skilled with her. Maybe time to get serious about learning her as I may finally get around to Fintech’s challenge.
May open one more in another few days - will see how I’m feeling about spending more units. Only pulled 1 7* from the valiants - a first time dupe on my Patriot, so pretty meh. Got enough 7* shards to spin out a basic champ, and got a first time dup on my Attuma which is much better obviously.
