To solve the problem of finding the mean and standard deviation of the number of aces drawn from a well-shuffled deck of 52 cards when two cards are drawn successively with replacement, we can follow these steps: ### Step 1: Define the Random Variable Let \( X \) be the random variable representing the number of aces drawn in two draws. ### Step 2: Identify Possible Values of \( X \) Since we are drawing two cards, the possible values of \( X \) are: - \( X = 0 \): No aces drawn ...
