    To find the probability of drawing 7 or more face cards (which includes Jacks, Queens, Kings, and Aces) from 8 random cards, we first need to recognize that in a standard deck of 52 cards, there are 16 face cards (4 each of Jacks, Queens, Kings, and Aces) and 36 non-face cards.

    We need to calculate the probabilities of two cases:

    1. Drawing exactly 7 face cards and 1 non-face card.
    2. Drawing 8 face cards.

    For both, we can use the hypergeometric distribution. The general formula for the hypergeometric probability is:

    [ P(X = k) = \frac{{\binom{K}{k} \binom{N-K}{n-k}}}{{\binom{N}{n}}} ]

    Where:

    • ( N ) is the total number of items (cards in the deck, 52),
    • ( K ) is the total number of items of one type (face cards, 16),
    • ( n ) is the number of items to be drawn (8),
    • ( k ) is the number of items of one type to be drawn.

    For 7 face cards: [ P(X = 7) = \frac{{\binom{16}{7} \binom{36}{1}}}{{\binom{52}{8}}} ]

    For 8 face cards: [ P(X = 8) = \frac{{\binom{16}{8} \binom{36}{0}}}{{\binom{52}{8}}} ]

    We will calculate these probabilities to get the final answer.

    The probability of drawing 7 or more face cards (Jacks, Queens, Kings, Aces) from 8 random playing cards is approximately 0.0564%, or about 1 in 1772. This is a rare event given the small proportion of face cards in a standard deck.

    I grew up in Georgia, and when I was in elementary school, my mom had a friend with a couple older boys who lived in California. Every year, when they would grow out of their clothes, I would get a giant box of the coolest California clothes like Op and Quicksilver. I used to think I was so cool in school.








  • I’ve generally had good luck with hardware and things just worked under linux. But one day I upgraded a few machines on my network to 2.5G ethernet. Several already had the ports, but my little NUC NAS box didn’t, so I installed a 2.5G usb ethernet dongle. No matter what I did, I couldn’t get it to work. It would show up and NM would act like it was up and there were no errors or anything, but it just wouldn’t actually function.

    Eventually, I found out that it has a built in USB data partition that contains the drivers for windows. The card was coming up as a usb disk first when the hardware was assigned and not a network card which it should have been.

    I had to write a blacklist the usb modules first, which I had done before, but I had to also write a udev rule to automatically add the network card and driver on boot. It wasn’t that difficult to actually do, but I had just never had to do anything with udev rules before. Took me a good three days of troubleshooting to finally get everything to work correctly on boot.

    It’s because it actually is a security risk with the Chinese government having the ability to do who knows what with a frightening amount of data. There is also the option of selling the company to one that isn’t related to the Communist Party government, but no one seems to be talking about that option.

    The only slippery slope is more apps owned by a foreign government that is not exactly our friend.

    If the app was owned by North Korea, would you be cool with it too?They aren’t banning Instagram and Facebook.
