Can someone do the state assignment and next state equations

Can someone do the state assignment and next state equations

Scenario: The object of the game is to score
exactly 15 points in as few rolls of the die as possible. After each roll, the player can choose to
add the current die value to his or her score or not, unless the die value is six, in which case it is
automatically added to the player’s score. If the player’s score exceeds 15, the player loses. If the
player’s score is equal to 15, the player wins. Play continues until the player reaches or exceeds
15 points.

Thank you
