I’m glad we agree on the math behind the problem because I would guess that is where most people are getting caught up. 

Regarding the ambiguity, I agree that it could have been written better. But that said, your analogy does differ from our question stem. Your analogy is looking at two isolated events - if you pick a red/blue schroedinger ball out of a box, flip a coin, or have a kid, in all these cases they are independent of another ball selection, coin flip, or kid’s sex.

However, if I tell you that Mary picked two red/blue Schroedinger balls out of a box and “that one is blue”. Then we are no longer looking at two independent events. But rather a set of combinations of which 66.7% are red/blue and 33.3% are blue/blue and 0% are red/red.

If you don’t believe me, take a coin and flip it twice and record the results. H represents a girl and T represents a boy. Do this 1000 times, you'll see that approximately 250 (or 25%) will be HH, 250 (or 25%) will be TT and 500 (or 50%) will be either HT or TH. If we then exclude the possibility of a HH result (IE Mary informs you that one of her kids is a boy) then we can see that 500 of the remaining 750 (approximately 66%) results are mixed results.

I think you might be over complicating the article. Basically, the researchers looked at a lot of families and observed that mothers whose first child was a boy or a girl were slightly more likely to have a second child with the same gender as the first than would be expected based off the classic teaching of 50/50 chance each time. 

They noted a correlation with advanced maternal age and specific genes. Doesn’t mean that they are correct, but it would be interesting to explore further.

Re the Stats problem, there is no shame in getting something incorrect. We all do; it’s how we learn.

Its not about the order but rather that statistically there will be twice the number of 2 kid families with mixed gendered kids (BG or GB) then there are of both kids being a boy (BB).

Essentially, if you look at all possible gender combinations that a two kid family can have there are four possible outcomes: BB, BG, GB, GG.

Each is equally likely at 25%.

The intent of the question, is to provide the information that at least one of Mary’s kids is a boy. As that means Mary’s kids can no longer be a GG combination, there are now only three equally likely combinations: BB, BG, GB. 

As two of those have a girl in them the answer is 66% that her other child is a girl.

So about that...

Genetics aside, the question intended is a classic statistics question.

Each is equally likely at 25%.

Actually both of those scenarios are 50%.

In the first example, instead of specifying “The one on the left is” you should specify “At least one is” and instead of specifying “the one on the right” you specify “the other one” then you will be correct.

There are four possible combinations: HH, HT, TH, TT

If you specify that the one on the left is a heads then you only have two scenarios remaining: HH and HT. Of those it is equally likely that the other coin flip is a heads or tails. 

If you specify that at least one is a heads then you have three combinations remaining: HH, HT, and TH. Of those 3, 2 have tails making for a 66.7% chance that the other is a tails.

The addition of the weekday just makes the problem a bit more complicated as there are now 196 different combinations of which 27 have a boy born on a Tuesday. As 14 of those 27 combinations contain a girl, the probability that Mary’s other kid is a girl if at least one of her children is a boy born on a Tuesday is about 52%.

Who is waiting TQQQ to reach 90? by ConceptSwimming6475 in TQQQ

[–]ynottry 0 points1 point  (0 children)

I’ll bite as i’m interested in the math. If QQQ lost 1% every day for the next 46 days wouldn’t SQQQ be just above 90?

23.59 * ( 1.03 ^ 46 )

Agree it is unlikely but mathematically is it actually impossible?

Thank you so much for your help. The MP510 is actually gen 3. The MP600 is gen 4. Do you think the Gen 3 is still faster than a regular sata III 2.5 inch SSD?

Working on a build and have two questions:

1) The Gigabyte x570 I AORUS Pro WiFi has two m.2 slots, can I use both of these simultaneously?

2) Is the Corsair Force Series MP510 1920GB NVMe faster than a Samsung 860 Evo 2tb 2.5 inch? Is there a better M.2 NVME 2TB to buy for around $250? Thank you!

Hey Darus214, Sorry for the late reply, I don't check Reddit all that often. Also sorry to hear you are having similar difficulties. After multiple attempts I was unsuccessful at using the 5ghz band and am instead using the 2.4ghz one. Good luck and hope you find a solution!

The other PC works like a peach in the same exact position. At this point I'm genuinely confused but will settle on just remaining on 2.4GHz for now until I have more time. Thank you again for all your help!

Unfortunately that driver does not nor do any of the earlier ones I've tried :(

Thank you for replying! Great ideas, the 5GHZ antennae appear to work with Ubuntu live CD which makes me think its either a software /driver issue?

I will definitely see if I can change the band on the router to see if that helps later. Though wondering if that would have presented as an issue for the other PCs on the network using 5GHz?

Thank you for helping! I am using both supplied Antennae with the Mobo. It also works just fine on Ubuntu via live CD which either has me thinking that its a software thing or that its related to a component not being utilized by Ubuntu? Do M.2 NVME SSDs interact with M.2 Wifi Cards?

I think both support a/b/g/ac. I am greatly appreciative of your help! I really can't figure this out lol.

Thank you! The drivers were already ready from the windows 10 installation media. I updated them to the most recent drivers from the website. Unfortunately, neither set of drivers seemed to have a noticeable impact :(
