Three dice are thrown simultaneously. Let \(\mathrm{A}\) be the event, "The sum is three," and \(\mathrm{B}\) the event, "The sum is four." Which of the following statements is true?
The event \(\mathrm{B}\) is more likely than the event \(\mathrm{A}\).
The event \(\mathrm{A}\) is more probable than the event \(\mathrm{B}\).
Both events are equally likely.
The probability of the event \(\mathrm{A}\) is three times greater than the probability of the event \(\mathrm{B}\).
