For the unfair dice, the chance of observing 3 is 1/3. If you roll dice enough times you definitely will see “streaks” of numbers, like a run of high or low numbers or something, and we’ll talk later about why that is, but it doesn’t mean the dice are “hot” or “cold”; if you roll a standard d6 and get two 6s in a row, the probability of rolling another 6 is… exactly 1/6.
