1 . ( 6 pts ) What are the mean and standard deviation of the following discrete probabilitydistribution ? Show your work . If you use a calculator , you must identify the list ( s ) and/ orfunction ( S ) , with input ( S ) , you used . Give your answer to two decimal places .P ( X )2.150 . 10510. 4260. 332 . ( 3 pts ) Suppose we have a 20% chance of winning a game and play 30 times . What is theprobability we win the game exactly 17 times ? Show your work . If you use a calculator ,you must identify the list ( s ) and / or function ( s ) , with input ( s ) , you used . Give your answer tothree decimal places .3 .
