You are playing a card came, and the probability that you will win a game is p = 0.57. If you play the game 387 times, what is the most likely number of wins? (Round answer to one decimal place.) με Let X represent the number of games (out of 387) that you win. Find the standard deviation for the probability 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 the maximum usual value is µ+20. You already found μ and o for the random variable X.
