"""
    Calculates the expected value given a list of probabilities and corresponding values.
    Parameters:
    prob (list): A list of probabilities.
    values (list): A list of corresponding values.
    Returns:
    float: The expected value.
    Raises:
    ValueError: If the number of probabilities and values are not the same.
