Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace the card, and draw another card. You repeat this process until you have drawn 17 cards in all. What is the probability of drawing at least 6 diamonds? For the experiment above, let X denote the number of diamonds that are drawn. For this random variable, find its expected value and standard deviation. E(X) %3D

Given that z is a standard normal random variable, find z for each situation (to 2 decimals). The area to the right of z is 0.1151 and 0.3409. The area to the left of z is 0.6951.

You are playing a card game, and the probability that you will win a game is p=0.13If you play the game 1043 times, what is the most likely number of wins?(Round answer to one decimal place.)μ = Let X represent the number of games (out of 1043) that you win. Find the standard deviation for the probability distribution of X.(Round answer to two decimal places.)σ = The range rule of thumb specifies that the minimum usual value for a random variable is μ–2σ and the maximum usual value is μ+2σ. You already found μμ and σσ 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 =
