I think I’m missing something obvious in my interpretation of this question: my understanding is you roll 1 die; and if that die is at least 3, you roll again. So in that case, the minimum sum you could have would be 3 (first die’s minimum possible value) + 1 (second die’s minimum possible value) being 4. However, the images all have sums below 4; are sums intended to also be counted if there’s only 1 dice roll?
Edit: Similarly for question 7 above; is the sum supposed to only count if both dice are rolled, or does it also count if only 1 die is rolled?
