Eliza is playing roulette on her computer for play money. to play, she “spins” a wheel that consists of 18 red numbers, 18 black numbers, and 2 numbers that are neither red nor black. before spinning, she bets $7.60 that the number will come up black. if she wins, she gets back the amount she bet plus $7.60, and if she loses, she must forfeit the amount she bet. if she spins the wheel many times, making the same bet each time, how much can she expect to lose per spin, on average?
