In the game of roulette. a player can place a $4 bet on the number 9 and have a 38 probability of winning. If the metal ball lands on 9. the player gets to keep the $4 paid to play the game and the player is awarded an additional $140. Otherwise. the player is awarded nothing and the casino takes the player's $4. What is the expected value of the game to the player? If you played the game 1000 times. how much would you expect to lose? Note that the expected value is the amount. on average. one would expect to gain or lose each game.
The expected value is $11. (Round to the nearest cent as needed.) The player would expect to lose about $n. (Round to the nearest cent as needed.)
Find the mean variance. and standard deviation of the binomial distribution with the given values of n and p. n=121. p=0.84
The mean. 1.t. is 1101 61 (Round to the nearest tenth as needed.)
The variance. a2. is ?. (Round to the nearest tenth as needed.) The standard deviation a. is ?. (Round to the nearest tenth as needed.)
