In this video, we calculate probabilities involving rolling a non-standard die twice. The die has two faces with '1', three faces with '2', and one face with '3'. We'll determine the probability of specific outcomes, such as getting a sum of 6, a sum of 4, getting at least one '3', getting at most one '3', and the probability that the second throw results in a higher number than the first.
