Explanation Given: In American roulette there are 38 compartments numbered 1 through 36 , 0 , and 00 . Approach: The expected value of X , denoted by E ( X ) is given by, E ( X ) = x 1 p 1 + x 2 p 2 + ........ + x n p n Here, x 1 , x 2 , ........ , x n are the values of random variable X with associated probabilities p 1 , p 2 , ....... , p n respectively. Calculation: Let X denote the winnings on the $ 1 bet. X = $ 17 , If the player wins, the associated probability is 2 38 . And, X = $ ( − 1 ) , If the player loses, the associated probability is 36 38
