Some card game problems, dice roll problems, coin toss problems. Not your classical problems though, much more casino-like, but far more convoluted with not enough of time to solve them analytically on the spot (you are not expected to solve them completely, only give approximate solutions).
Some probability puzzles
Questions mixing, for example, market making and dice rolls: in the first rounds this could be to make a market (buy/sell prices, number of items to buy/sell) on the sum or the product of two 6-sided dice.
Standard probability/statistics questions, very similar to the ones that have already been written here.
asked not to disclose q but the math rounds got much more open ended as it went which made it easier for me
Standard puzzles and extreme basic python and pandas

One coin with probability 0.8 of landing with a head, what is the expected number of coin tosses to see 2 consecutive heads?
Some stats qns (jane street has a string non disclosure policy, apologies)
