As you argued, probability to hit a 6 on each roll is 1/6, but the sum overcounts rolling 6 twice, so the actual probability of rolling 6 on either one or both roll is $$ \frac{1}{6} + \frac{1}{6} - \frac{1}{36 ... WebDetails. These functions compute rolling means, maximums, medians, and sums respectively and are thus similar to rollapply but are optimized for speed.. Currently, there …
