To solve the problem of finding the mean, variance, and standard deviation of the number of kings drawn from a pack of 52 cards when two cards are drawn, we will follow these steps: ### Step 1: Define the Random Variable Let \( X \) be the random variable representing the number of kings drawn. The possible values of \( X \) are: - \( X = 0 \): No kings drawn - \( X = 1 \): One king drawn - \( X = 2 \): Two kings drawn ...
