The player spins a spinner twice. On each spin the player can get a 1 or a 4 ; P(1) = .4 and P(4) = .6. The random variable X = the sum of the two spins. If X is an even number the player wins that many dollars ($2 or $8). If X is an odd number the player loses that many dollars ( $5). What is the expected value of this game to the player?
