        <h2>Understanding Probability</h2>

        <p>**Probability** is a measure of the likelihood that a given event will occur. The value of probability ranges from 0 (impossible event) to 1 (certain event).</p>

        <div class="step">

            <div>
                <h4>Formula for Probability</h4>
                <p>The probability of an event is calculated using the formula:</p>
                <pre>Probability (P) = Number of favorable outcomes / Total number of possible outcomes</pre>
            </div>
        </div>

        <h3>Example: Rolling a Die</h3>
        <div class="example-box">
            <p><strong>Example 1:</strong> What is the probability of rolling a 3 on a fair six-sided die?</p>
            <pre>Step 1: Total number of possible outcomes = 6 (since the die has six sides).
Step 2: Number of favorable outcomes = 1 (only one side has a 3).
Step 3: Probability = 1/6 ≈ 0.167.</pre>
        </div>

        <h3>Example: Drawing a Card</h3>
        <div class="example-box">
            <p><strong>Example 2:</strong> What is the probability of drawing a heart from a standard deck of 52 cards?</p>
            <pre>Step 1: Total number of possible outcomes = 52 (total number of cards).
Step 2: Number of favorable outcomes = 13 (since there are 13 hearts in a deck).
Step 3: Probability = 13/52 = 1/4 = 0.25.</pre>
        </div>

        <h3>Try It Yourself:</h3>
        <p>Calculate the probability of drawing a king from a standard deck of 52 playing cards.</p>
        <pre>Hint: There are 4 kings in the deck. Total number of cards = 52.</pre>
        <p>The formula is the same as in the examples above. Try calculating the probability!</p>
