Two cards are drawn successively without replacement from a well shuffled deck of cards . Find the mean and standard variation of the random variable X , where X is the number of aces .

Explanation

To solve the problem of finding the mean and standard deviation of the random variable \(X\), where \(X\) is the number of aces drawn when two cards are drawn successively without replacement from a well-shuffled deck of cards, we can follow these steps:

### Step 1: Define the Random Variable
Let \(X\) be the random variable representing the number of aces drawn. The possible values of \(X\) are 0, 1, or 2.

### Step 2: Calculate the Probabilities
We need to calculate the probabilities for each value of \(X\).
