For many years, organized crime ran a numbers game that is now run legally by many state governments. The player selects a three-digit number from 000 to 999 . There are 1000 such numbers. A bet of $4 is placed on a number, say number 115. If the number is selected, the player wins $2500. If any other number is selected, the player wins nothing. Find the expected value for this game and describe what this means. The expected value of the numbers game is \\square$ . (Round to the nearest cent.)
