    Probability in a card game

    I play a card game called 'Yu-GiOh!'. For those who don't know how this game works, that will be separate paragraphs at the bottom of the page. I have a deck, and I'm looking for the chances of getting a specific one of these using only the starting hand. The numbers are below, (a) and (b) etc...

    The probability that I am missing only one tile

    Background I recently became fascinated (really!) in this probability problem. I have done quite a bit of work to figure out the answer myself--which I am willing to share with anyone if that will help. But I haven't got an answer yet and I am also just wondering if there is anyone else out...

    Game Probability Question

    Hi, I am playing a game. I win with an 88% chance and lose with 12% probability. If I have won 20 games in a row what is the probabilty that I will lose the next game. If you can figure out the answer and provide also the calculation logic that would be great. Thanks B

    Hard probability question/game-binomial dist.

    Consider 50 people and series of 10 rooms. Each room has, for example, 5 doors that will open to the next room with known (totally known, including in later rooms), but different probabilities. Everyone begins in room 1, and each person selects a door. If that door opens, all of the people...

    Imagine a game where you throw a ball in to a box where are three sticks; the probability of the ball to throw down one stick is 75%, two sticks is 20% and the three sticks is 5% Additionally, when you throw the ball, it passes through a random accelerating mechanism that can make the ball pass...

    High/low between 1-10 game odds

    I'm trying to figure out the odds for a game where a number between 1 and 10 are drawn randomly, and the player must guess if the next number is higher or lower than the previous number. There can't be consecutive numbers. And to make the calculation more difficult, the player can make three...

    Game probability problem

    Two armies of n attackers and m defenders do battle. If n=1, then there is 1 attacking die; if n=2 there are 2 attacking dice; if n \geq 3 there are 3 attacking dice. If m=1 there is 1 defending die; if m \geq 2 there are 2 defending dice. (You may recognize this as Risk, and you'd be right.)...
