In a game, the player throws a coin and a regular die simultaneously. If the coin shows a head, the player's score is the score on the die. If the coin shows a tail, then the player's score is twice the score on the die. What is the probability that the score is even?

In a game, a player will have to throw a tetrahedral die and a coin at the same time. If he get a tail on the coin, the game will stop and he will receive the point based on the side facing down on the tetrahedral die. If he get a head on the coin, he will then throw the die again and he will receive the point based on the product of the 2 throws on the die. What are the number of different possible score a player can get?

In a game, a player will have to throw a tetrahedral die and a coin at the same time. If he get a tail on the coin, the game will stop and he will receive the point based on the side facing down on the tetrahedral die. If he get a head on the coin, he will then throw the die again and he will receive the point based on the product of the 2 throws on the die. If the player can only wins if he/she get above a certain value. What is the value if the game only allows 2 / 5 of the players to win?
