I am doing a math project over probability and i chose to study the game blackjack. Can you tell me the chances (in fractions) of getting 21 on the first hand, the first hit (if you have two cards, and say hit me) and the third hit? (with a game played between the dealer and one person)

I know that the hi lo system works in blackjack because of deck flucuations, but in poker, could the same technique be applied to help guess the probability of beneficial cards coming up, or could it be used to guess a players hand?

Got to do a assignment and it is totally completely whacked. If some has played roulette than how is the probability related to the odd that game

In the roulette I can bid on red or black every time and every time have the same probability of winning (double) or losing (all). I wonder if there is any other game or even financial/speculative product like that.

Thanks.

Each person in a room of people has two bingo cards. Only the first person called can win, and each card is randomly selected but unique with no repeat cards. Does each person have the same chance of scoring bingo? Does similarity between cards owned by the same person lower the probability of that person scoring bingo first? If so, can trading one of your two cards with another player increase both of your chances of winning simultaneously?

Im doing an assignment and it is completely whacked but anyway i have to do it and if anyone has played roulette than how is the probability related to the odds of that gambling game?
