Optiver interview probabilities
Hello guys,
I am having an interview with optiver and I am looking for any book that could help me prepare for probability queStions involving cards. (There are also questions about variance).I heard that optiver uses them a lot. If anyone has any clue about the questions I would be really grateful. Thank you for your help !!
There's 52 cards in a deck. 4 suits. A,2-10,j,q,k. 4 of each. That's all you need to know and should be able to do any probability in your head with that information alone. I went through the interview process and if you need a book to help with any basic card probability you're fucked tbh.
I heard something like what’s the expectation of drawing a card if I remove 7,8 and 5 from the deck. Or the variance of such an event . Excuse me but that’s not easy to compute when you are in front of recruiters with a 6 second limit ... I don’t know if it was your case
