You are correct. The sum of the 2 highest dice rolls can never be 3. I apologize for the mistake in my previous response.

Here's the updated implementation of the code that correctly handles the scenario where all 3 dice show 1, includes the sum of 2 in the histogram, and accepts a command-line argument to specify the total number of rolls:

    import random
    import matplotlib.pyplot as plt
    import sys

    # Check if the total number of rolls argument is provided in the command line
    if len(sys.argv) > 1:
        total_rolls = int(sys.argv[1])
    else:
        total_rolls = 100  # Default total rolls if argument is not provided

    # Initialize an empty list to store the roll results
    results = []

    # Roll the dice the specified number of times
    for i in range(total_rolls):
        # Roll 3 d20 dice
        rolls = [random.randint(1, 20) for _ in range(3)]
    
        # Sort the rolls in descending order
        rolls.sort(reverse=True)
    
        # Get the sum of the two highest rolls and add it to the results list
        if rolls[1] == 1 and rolls[0] == 1:
        # If all 3 rolls are 1, add 2 to the results list
            results.append(2)
        else:
            results.append(rolls[0] + rolls[1])
    
    # Generate a histogram of the frequencies of each number
    plt.hist(results, bins=range(2, 41), align='left', rwidth=0.8)
    plt.xticks(range(2, 41))
    plt.xlabel('Sum of two highest rolls')
    plt.ylabel('Frequency')
    plt.show()

The updated code first checks if a command-line argument is provided and uses it to set the total number of rolls. If no argument is provided, it sets the default total rolls to 100.

The rest of the code is similar to the previous implementation. It rolls 3 d20 dice the specified number of times, sorts the rolls in descending order, and gets the sum of the two highest rolls. If all 3 rolls are 1, it adds 2 to the `results` list. Otherwise, it adds the sum of the two highest rolls to the `results` list.

Finally, the code generates a histogram of the frequencies of each number using the `plt.hist()` function from `matplotlib.pyplot`. The `bins` parameter specifies the range of the histogram bins, which is set to range from 2 (the lowest possible sum of the two highest rolls, which occurs when all 3 rolls are 1) to 40 (the highest possible sum of the two highest rolls). The `xticks` parameter specifies the range of x-axis ticks, which is set to range from 2 to 40. The `xlabel` and `ylabel` functions are used to set the labels for the x-axis and y-axis, respectively.

To run the script with a specified number of rolls, you can call the script from the command line with an argument that defines the total number of rolls, like this:

    python script.py 200

This will run the script with 200 rolls. If no argument is provided, the default total rolls will be 100.
