You are playing a card came, and the probability that you will win a game is pIf you play the game 723 times, what is the most likely number of wins?(Round answer to one decimal place.)μ == 0.31.Let X represent the number of games (out of 723) that you win. Find the standard deviation for theprobability distribution of X.(Round answer to two decimal places.)0 =The range rule of thumb specifies that the minimum usual value for a random variable is µ-20 and themaximum usual value is µ+20. You already found u and o for the random variable X.Use the range rule of thumb to find the usual range of X values. Enter answer as an interval using square-brackets and only whole numbers.usual values=
