A lottery game works as follows: The player draws a numbered ball at a random from an urn containing five balls numbered 1,2,3,4,and 5. If the number on the ball is even, the player loses the game and receives no points; if the number on the ball is odd, the player receives the number of points indicated on the ball. Afterwords, he or she replaces the ball in the urn and draws again. On each subsequent turn, the player loses the game if the total of the all the numbers drawn becomes even, and gets another turn( after receiving the number of points indicated on the ball and then replacing the ball in the urn) each time the total remains odd.
What is the probability that the player accumulates exactly 7 points and then loses on the next turn?
OA is [spoiler]198/3125[/spoiler]
